René Raaijmakers talks to the innovators driving the high-tech industry. Listen (in Dutch) to researchers, developers and decision-makers speak about trends, technology, business and their motivations. In the second edition of the Bits&Chips podcast, Jos Maas (CEO of Nearfield Instruments).
Affordable phased arrays, built using low-cost silicon chips, have become an essential technology for high-data-rate terrestrial (5G) and satellite (satcom) systems because of their high gain, electronically steerable patterns, narrow beam widths, high tolerance to interference and adaptive nulling capabilities. They have also become the backbone of all LEO and MEO satellites (non-geostationary), both at the payload level and at the user terminal. High-EIRP, high-performance systems at X, Ku and Ka-bands and 60 GHz with analog and digital beamforming capabilities and with multiple beams are now available at low cost due to the immense commercial investments placed in the past 5 years. These advances are reshaping our communication and radar/sensor systems, as we work to change our world from the Marconi era given by low-gain broadcast and user-terminal antennas to the directive communications era where every antenna, every beam, every sensor is electronically steered. This talk summarizes our work in this area and presents a roadmap for the future.
Gabriel Rebeiz is Member of the National Academy (elected for his work on phased arrays) and a Distinguished Professor and the Wireless Communications Industry Endowed Chair at the University of California, San Diego. He is an IEEE Fellow, and is the recipient of the IEEE MTT Microwave Prize (2000, 2014, 2020), all for phased arrays. His 2×2 and 4×4 RF beamforming architectures are now used by Renesas, ADI, NXP, Infineon, Sivers, Qualcomm, Intel, Samsung, Boeing and others, and most companies developing communication and radar systems. All satcom affordable phased arrays are based on his work and architectures.

With the shipment of its first system to a high-end chip manufacturer, Nearfield Instruments proves that the semiconductor market is very much open to innovative solutions for advanced process control metrology. This first product, Quadra, can measure in-line and in great detail (ångstroms) the on-surface high-aspect-ratio (10:1) features of integrated circuits. The company is now scaling up to deliver dozens of its scanning probe metrology systems per year.
Nearfield founder Hamed Sadeghian foresees the Quadra metrology platform to be the basis for several products and product lines. All of them will solve different problems the semiconductor industry is facing to follow Moore’s Law with its ever smaller and 3D features. Nearfield is expecting to deliver its second product line based on the Quadra platform next year. This system will be able to image, non-destructively, subsurface structures with nano-precision.
In this talk, Hamed Sadeghian will highlight the major requirements for developing non-destructive 3D high-volume manufacturing metrology equipment in the semiconductor industry, the architecture of Quadra (including software) and the challenges faced and overcome. He will also address the impact of the system architecture on the outsourcing strategy to the high-tech supply chain.

In the automotive industry, Aspice is used for measuring an organization’s capability to develop high-quality software. Companies supplying software to automotive manufacturers are required to have a minimum maturity level to ensure that they deliver that high quality. Still, having high-quality processes in place and complying with them is no guarantee. To see why that is and what else is needed to assure high quality software, we first need to understand the many different aspects of software quality and the influence they have. In this talk, Ger Cloudt will present a holistic view on software quality using the 1+3 SQM approach, addressing the consequences of high or low quality for each of the four defined quality types.
Since the beginning of 2019, Arjen van Elteren is lead software architect at Nearfield Instruments. From 2009-2019, he worked as a senior software engineer/architect for the Leiden Observatory . Before that, he was as a software engineer atcompanies such as ASM and HP.
The Dutch high-tech equipment builders are all leaders in their markets, owing to their strength to handle the complexity of the systems they create. This talk will discuss how the industry must now prepare for the next levels of complexity, as their systems are getting integrated in complex workflows (effectively becoming systems-of-systems), are including more and more AI and are becoming subject to continuous upgrades. This calls for a new generation of methodologies and ways-of-working, like MBSE (model-based systems engineering) and open-source tooling. In addition, it calls for quickly getting a new generation of engineers up to speed, moving from intricate and outdated documentation to models as means to quickly capture and share the essence of complex systems. And finally, it raises the question how to educate the next generation of engineers to equip them with the systems thinking skills needed to deal with this next generation of complexity.

Imagine a system that, once turned on, will stay operational for the rest of its life. Hardware parts may break or go obsolete, software components may crash, cyber attacks are part of everyday life and knowledge of the system itself becomes volatile. Critical systems in general are software intensive and have life times of 30 years and longer. Just imagine how such systems should be designed and what challenges we have to conquer. Together with partners, Thales has developed an open architecture (Inaetics) in 2016 that addresses these challenges. Today, a number of areas for improvements have been identified and put on the agenda for the Inaetics Extended project. This talk will present the challenges we need to conquer.
René van Hees worked for several software companies in both the Netherlands and Germany before he started at Thales Netherlands in 2002. In his role of chief software architect, he is responsible for all technological, process, methodology, architectural and innovation-related aspects concerning the development of (real-time embedded) radar sensor software.
What does this part of my software do? How does it behave in different situations? And why does a software change cause a regression in a seemingly unrelated part of my system? Understanding software behavior is becoming more and more essential to handle the complexity of high-tech systems. ESI developed and applied model inference to automatically obtain software behavior models that provide valuable insights. These models can be compared to quickly determine the impact of software changes on the system behavior, and locate potential regressions before the software is deployed. How can this help you?

He makes academic formal methods ready for industrial use through applied research, bringing academia and industry together for win-win collaboration and creating real impact together.
At Nexperia ITEC, we already have a 30+ years history in back-end assembly equipment development. This has resulted in a significant large and complex codebase. In the dynamic development environment of ITEC, we started rejuvenating our codebase for more efficient and structured code development. For this, we have started a partnership with ESI in the Bright program. One of the goals is to rejuvenate our codebase by applying innovative tooling to support the software refactoring tasks. This talk will present the activity of automatically transferring visual inspections integrated in the Adat die bonder software application. Since there are many instances of visual inspection tasks connected up to 14 camera positions in this system, the main challenge was to run data-driven code analysis to learn the specific instance of inspection calls in the application. By doing automatic transformations, a serious development speed-up, an improved code quality and a more maintainable code base have been achieved.
Raymond Rosmalen has more than 20 years of experience in the field of machine vision.

To keep your competitive edge, you need to innovate, which means to transform your organization to adopt new technologies to perform better in the end. In practice, this is very challenging. What is the added value of the new technology? What processes do you need to create or adapt to capture this added value? What is the impact on your teams and their required skills and mindsets? These are three major questions that you need to address when considering new technology to improve business. At Thermo Fisher Scientific, we are working on using model-based testing techniques to manage the complexity of developing, testing and maintaining the interfaces between software components. These techniques enable via modeling the automatic generation and execution of test cases. At ICT, we are supporting Thermo Fisher Scientific in adopting these new techniques. Thermo Fisher Scientific is a large organization, their software is complex, their market is highly competitive and their customers highly demanding. This talk explains how ICT and Thermo Fisher Scientific are answering the three major questions above. At the end, the main question remains: how do we effectively explore and discover the added value of a technology like model-based testing, the processes and the skills required to succeed?

To move quantum computers from the proof-of-principle stage towards real-life applications, many engineering challenges need to be overcome. Amongst these are the generation and routing of control signals. As most of the platforms require signal frequencies between DC and 20 GHz, these challenges are for a large part RF engineering challenges. The fundamentally sensitive nature of qubits drastically complicates these: qubits need to be placed at ultralow temperatures (<< 1 K) and control signals require extremely precise timings (<< 1 ns), low signal noise, distortion, drift and crosstalk. Qblox and Delft Circuits work precisely on these topics and provide quantum computer developers around the world with their state-of-the-art control technology. This talk starts at the level of the quantum bits to understand their control needs at a fundamental level and goes up into the stack layer by layer to discuss challenges in the cabling (Delft Circuits), the control electronics (Qblox) and the digital infrastructure for feedback (Qblox).
Niels Bultink specializes in controlling quantum computers, performing the first feedback on solid-state qubits in 2012. His PhD research with Leonardo DiCarlo at Delft University of Technology has led to more than ten scientific publications centered around fault-tolerant quantum computing with superconducting circuits. The work at Qutech enabled the control of setups with up to 50 qubits and has now found its way to the market via the company Qblox. With Qblox’s new and industrialized generation of control stacks, he is paving the way for quantum computer integrators worldwide to reach practical applications in quantum computing.

Intelligent sensing will be central in providing a seamless user experience in electronic devices – headphones that understand the difference between speech and background noise, security cameras that can differentiate between humans and pets, wearables that can detect if you’re falling ill. However, the narrow power envelope of these battery-powered devices is often a significant obstacle in realizing rich application functionalities based on traditional neural networks. Innatera employs a radically different approach to processing data efficiently at the sensor edge. Using brain-inspired spiking neural networks atop a programmable analog-mixed signal architecture, Innatera’s spiking neural processor enables always-on sensing applications within an ultra-low power budget.

Currently, she is CEO of Picoo; she manages general affairs and is responsible for game design, strategic planning and customer relations.
You want to stay ahead of your competitors by bringing the best product to the market, at the right time and at the right price point. Developing your own custom chip (ASIC) could be the best strategy for you. With one single-chip implementation, you could boost computational performance, massively cut power consumption and product size, and reduce unit cost. Moreover, ASICs are very difficult to copy, so protecting your IP is relatively straightforward. Despite these obvious advantages, creating an ASIC is often perceived as a difficult process – with development cost and time as the main hurdles. This talk will demonstrate that this perception is often no longer valid. ASIC development is well within reach for many companies, even if they’re not yet acquainted with the process. As director of business development at Imec.IC-link, Bas Dorren will talk from his experience of managing many ASIC projects in a wide range of technologies for a large customer base worldwide. He will explain what it takes to make an ASIC in terms of knowledge, cost and time. And he will make clear what the benefits could be for you.
Bas Dorren spent more than 20 years in various technical and commercial roles of several semiconductor companies. More than 10 years ago, he joined Imec.IC-link, Imec’s ASIC services group. Currently, he manages the business development activities. His team provides flexible turnkey ASIC services, including ASIC development and supply chain services to startups, SMEs and established OEMs, as well as universities, IC design houses and system companies. Dorren holds an MSc degree in physics from Utrecht University and a PhD degree in physics from Eindhoven University of Technology.
Developing innovative high-tech equipment is a daunting challenge, especially for startups and scale-ups. Solid systems engineering and lots of organizing are required when working with partners from different fields of expertise (which is almost always the case). Generating new ideas and validating them in your next prototype can take a lot of time. And there is always the risk of drowning in specifications, procedures and organizational issues. But your engineers want to engineer! The solution? Do it Agile! Surprisingly, an Agile approach with short development cycles will also work in high-tech development. The key is taking smaller steps, dividing the components into really small functional units, which can be either software, programmable logic, electronics or mechanics. Next, project partners quickly build and develop these units in a parallel process or they can employ third parties such as prototyping services to do this. Finally, hardware and software units are integrated into a working prototype, ready to be tested. This way, the short cycles generate quick and frequent feedback on product feasibility. With an Agile approach to high-tech development, it becomes much easier to keep the focus on the technical development of the next prototype. It allows all partners to concentrate on building the best possible components. This talk will highlight the advantages of Agile high-tech development, using as an example real-life cases, such as the development of crucial components for a multi-beam scanning electron microscope.

Prior to that, he worked for 14 years at the Philips Natlab.
Although we don’t know exactly how wireless communications will look like beyond 2030, we may assume that we will most likely communicate using holograms and digital twins, and that the merge of real and virtual reality has happen in an hyper-reality internet. Such new ways of communications will demand a large capacity and ultra-low latency. Developing technologies to exploit the terahertz frequency spectrum to implement terabit data capacity wireless links seems a futuristic endeavor. This talk considers the role of photonics in tackling the challenge to realize systems to generate, detect, multiplex and process terabit volumes of data in wireless terahertz systems.

The promises of 1Gb/s+ cellular data connectivity made by 5G network roll-outs is confronting fixed network operators with the risk of being left behind. As a consequence, the capability of an operator to offer a stable, affordable and ubiquitous 1 Gb/s internet connection is now no longer considered the holy grail but the next step needed to stay competitive. Early deep-fiber roll-outs show that high customer interest and retention are not enough to build a viable business with nation-wide availability, even when wireline technology is used for the final curb to home connection. By introducing wireless CMOS mm-wave technology in the network, a more favorable split between up-front and at-signup installation cost is achieved and a much wider range of neighborhoods can be serviced. This talk presents some of the technologies and methodologies used to build a carrier-grade 60 GHz product for the fixed-wireless access market with a fully integrated CMOS transceiver phased-array IC at its core.
After obtaining his MSc and PhD at KU Leuven, Carl De Ranter began his career at RF Magic, an RFIC Startup in San Diego, CA. There he worked on terrestrial and satellite TV tuners and became design manager to help build the start-up ahead of its merger and IPO.

From 2015-2019, he consulted for a tier-1 smartphone chip supplier where he built the team that developed front-end RFIC IP shipping in over 100 million mobile phones. In 2019, he co-founded Pharrowtech, an Imec spin-off that develops mm-wave CMOS radio hardware and software for next-generation wireless applications.
While 5G is being rolled out, 6G is already on the horizon to further increase wireless data rates up to 100 Gb/s for new applications such as 3D holography. These high data rates are best accommodated in wide frequency bands above 100 GHz, such as the D-band (110-170 GHz). So far, the functionality of wireless transceivers has been mainly implemented using downscaled CMOS, which allows a high integration complexity while featuring very fast transistors. Today we have come to a point where CMOS downscaling no longer increases transistor speed. In combination with the low supply voltage of nanoscale CMOS, generation of power, especially at mm-wave frequencies, is challenging for CMOS. To generate sufficient transmit power, D-band transceivers will need to resort to non-CMOS technologies such as InP. This talk will discuss how the combination of the antenna array, required for beamforming, the active circuits from different IC technologies (CMOS and InP) and advanced 2.5D or 3D technology can result in a high-performance 6G wireless transceiver.
Mark Ingels received the MSc and PhD degrees in microelectronics from the ESAT-MICAS Laboratories of the KU Leuven in 1990 and 2000, respectively.

He joined Imec in 2005 and is now a principal member of technical staff in the Advanced RF research group working on mm-wave transceivers for future communication systems.
5G/6G wireless communication data bandwidth will get a large boost when we can efficiently exploit mm-wave and sub-THz frequencies that allow us to transmit over large contiguous bandwidths. To transmit at these carrier frequencies, engineers use active antenna arrays with beam steering to overcome the high path loss. Testing and validating these actively steered antenna arrays and beam steering algorithms is complex and expensive, often involving large chambers and over-the-air (OTA) measurements. This talk provides an overview of the different validation and test options for mm-wave active antenna array modules and related research and technology challenges. It will present NI’s current innovation activities around OTA measurements and discuss potential solutions to many of the challenges, enabling lower cost and thus broader adoption of the 5G/6G frequency bands.
In 1990, Marc Vanden Bossche received the PhD degree from Vrije Universiteit Brussel in electrical engineering focusing on the foundation of high-frequency large-signal network analysis. In 1991, he established a Hewlett-Packard R&D team in Belgium continuing to work on characterization and system-level modeling tools for high-frequency non-linear electrical components, leading to the expansion of the capabilities of VNAs beyond S-parameters. In collaboration with NIST, a phase calibration standard was established in the second half of the 90s, merging network and signal analysis. In June 2003, Vanden Bossche founded NMDG, which was acquired by NI in October 2012. At NI, he and his team introduced vector calibration techniques into the NI RF production test systems. Presently, he is technically leading the accurate characterization effort under modulation conditions at NI and scaling these efforts for over-the-air characterization.

In 2015, Anteverta was acquired and became part of Maury Microwave. His research interests include the development of advanced characterization setups for RF high-power and high-linearity amplifier design.
The fast and ever-increasing demand for high-speed data services has been motivating and leading to define the next generation of telecommunication systems. To take advantage of this opportunity, methods and techniques to design RF and MW subsystems must continue to evolve to meet the requirements that include spectral and energy efficiency and, on the other hand, to reduce costs and time to market. To deal with these challenges, important works have focused on modeling and simulating front-end designs to allow analysis and optimization at a system level. This talk will present a comprehensive methodology to extract a black-box model of a power amplifier for two application examples: the evaluation of linearization techniques and the front-end design of an advanced antenna system.
Wissam Saabe is an application engineer at Amcad Engineering. He received the Master Research degree in electronics and optics for telecommunication from the University of Limoges in France in 2013, and is currently working towards the PhD degree at the Research Institute on Microwave and Optical Communications XLIM, University of Limoges.

Millimeter and sub-millimeter waves are nowadays being widely adopted within a variety of applications developed across the high-tech industry, including high-resolution automotive radar sensors, but also the fifth and sixth generation mobile communications RF front-ends. These applications primarily consist of a system-in-package tightly integrated with radiating elements to ensure adequate electromagnetic performance. Managing the design of such devices is particularly challenging from a manufacturing capabilities and related tolerances point of view, as the size of the metallic features shrinks with the frequency increase, but also due to the fact the power densities significantly increase, potentially leading to thermal issues. As such, RF IC package engineers not only need to accurately predict the electromagnetic performance of their implementation but also need to assess adequate thermal dissipation of these complex devices starting from early phases, driving their decisions towards the best system-in-package design sign-off. This talk will showcase solutions aimed at addressing these multiphysics simulation needs.

There’s no denying that cloud computing has been a top technology over the past two decades. So many of us working from home since the start of the pandemic would have been impossible not that long ago. Even though the cloud is key for today, it can’t handle the technologies of the future. Self-driving cars are a perfect example. They need to make ultra-fast, perfectly accurate decisions. There’s no time to wait for data to be processed in a data center. This is where edge computing comes in. Edge computing cuts across the IoT – from home and work to the most complex of all, the vehicle. Coupled with the rising digitalization that leads to everything connected, high-performance edge compute platforms are transforming ecosystems and the development landscape. In this talk, Maarten Dirkzwager will share why mastering edge computing with the right level of safety and security is critical to enabling next-generation technologies.
Maarten Dirkzwager is responsible for corporate strategy and chief of staff to the NXP management team. He joined the company in 1996 at Philips. After several roles in central engineering, he moved to Philips Semiconductors in Hong Kong in 2005, where he was responsible for the innovation, efficiency and strategy of the discrete back-end factories. In 2009, he moved to the corporate strategy team in the Netherlands where he was involved in the transition of NXP to a profitable high-performance mixed-signal player. In 2015, he played a leading role in NXP’s acquisition and integration of Freescale, which resulted in creating one of the leading semiconductor companies and a leader in automotive semiconductors. In 2017 and 2018, he worked as head of strategy for ASML and AMS, after which he returned to NXP in early 2019.
