8:00am-8:30am Check-in

8:30am-8:45am Introductions

8:45-9:30am: Radiation effects on semiconductor devices

The focus of this first part is on both the momentary and long-term impact of ionizing radiation
on semiconductor materials and devices. Starting from the mechanisms on an atomic scale, the
impact of a charged particles in an integrated circuit is discussed. Different categories of socalled
Single-Event-Effects are discussed by using real-live examples and cases. The long-term
radiation impact, so-called total ionizing dose effects, is discussed for several devices and
technology nodes.

9:30-10:15am: Hardening techniques for integrated circuits

Depending on the circuit topology, different techniques exist to diminish the effect of ionizing
radiation. Digital as well as analog hardening techniques are discussed and trade-offs are
identified. These techniques can extend the lifetime of state-of-the-art integrated circuits in
severe ionizing environments. Protection mechanisms for Single-Event Effects reduce error rates
and Single Event Failures and Interrupts due to charged particles.

10:15am-10:30am: Break

10:30-11:15am: Radiation hardened integrated circuits and design cases.

In this part, several case studies will be covered ranging from digital circuits, RF integrated
circuits and power systems. The applications and scope of radiation tolerant integrated circuits
will be discussed, and the challenges foreseen in the future of harsh environment integrated
circuits. Physical implementation methods for fault tolerant digital circuits will also be covered.

11:15-12:00pm: Testing and experimental verification.

The final part of this course is dedicated to verification techniques for radiation tolerant circuits.
Different types of irradiation facilities and measurement techniques are discussed and compared
to existing radiation environments and measurement methods are. Apart from this, the use of
LASER-based test equipment is also discussed (Single-Photon Absorption and Two-Photon
Absorption). Techniques are compared and, based on previously obtained test results and
different application techniques of this infrastructure are demonstrated.

12:00pm-1:00pm: Lunch and networking

Speaker: Dr. Valentijn De Smedt

Bio: Dr. Valentijn De Smedt received his PhD degree from Katholieke Universiteit Leuven on the design of ultra-low-power time-based building blocks for wireless sensor networks in 2014. Between February 2014 and July 2017 he was employed at MinDCet as a Senior Design Engineer and was responsible for the IP development of ultra-high voltage (1 kV) high-power integrated power converters and motor drivers. From September 2016 to October 2017 he was part-time postdoctoral researcher at the KU Leuven technology campus in Geel. Since 2017 he is appointed as assistant professor in the ADVISE research group. The focus of his research is on radiation-tolerant control systems for power and sensing applications. At KU Leuven, he has been involved in both leadership and technical activities of the IEEE student branch and IEEE Benelux GOLD (Young Professionals). In November 2017 he founded the IEEE Benelux NPSS chapter, which he currently chairs.

Speaker: Dr. Jeffrey Prinzie

Bio: Dr. Jeffrey Prinzie received his PhD degree from KU Leuven in 2017 in the field of radiation tolerant integrated circuits with the ADVISE research group. During his PhD, he was part of the CERN micro-electronics research group in which he was collaborating on a TDC SoC and high speed multi-gigabit transceiver and he gained experience in the design and experimental testing of these circuits in nuclear facilities. His current research focuses on highly digital integrated circuits, digitally assisted analog- and RF integrated systems and time accurate circuits for high-energy physics, space and nuclear energy applications. Currently, he is also a visiting researcher at Mediatek wireless (United Kingdom) on ultra-fast locking digital RF-frequency synthesizers for 5G mobile systems.
