[paper] Flexible TFT Electronics

Hikmet Çeliker, Wim Dehaene and Kris Myny
Multi-project wafers for flexible thin-film electronics by independent foundries.

Abstract: Flexible and large-area electronics rely on thin-film transistors (TFTs) to make displays large-area image sensors, microprocessors, wearable healthcare patches, digital microfluidics, and more. Although silicon-based complementary metal–oxide–semiconductor (CMOS) chips are manufactured using several dies on a single wafer and the multi-project wafer concept enables the aggregation of various CMOS chip designs within the same die, TFT fabrication is currently lacking a fully verified, universal design approach. This increases the cost and complexity of manufacturing TFT-based flexible electronics, slowing down their integration into more mature applications and limiting the design complexity achievable by foundries. Here we show a stable and high-yield TFT platform for the fabless manufacturing of two mainstream TFT technologies, wafer-based amorphous indium–gallium–zinc oxide and panel-based low-temperature polycrystalline silicon, two key TFT technologies applicable to flexible substrates. We have designed the iconic 6502 microprocessor in both technologies as a use case to demonstrate and expand the multi-project wafer approach. Enabling the foundry model for TFTs, as an analogy of silicon CMOS technologies, can accelerate the growth and development of applications and technologies based on these devices.

Abstract: The radiation response of MOS transistors in a 22 nm Fully Depleted Silicon-On-Insulator (FDSOI) technology exposed to ultra-high total ionizing dose (TID) was investigated. Custom structures including n- and p-channel devices with different sizes and threshold voltage flavours were irradiated with X-rays up to a TID of 100 Mrad(SiO2) with different back-gate bias configurations, from −8 V to 2 V. The investigation revealed that the performance is significantly affected by TID, with the radiation response being dominated by the charge trapped in the buried oxide.

[webinar] Power WBG Semiconductor Technology Opportunities


"Power WBG Semiconductor Technology Opportunities"
webinar hosted by 
Dr. Victor Veliadis, 
Executive Director and CTO of PowerAmerica,

Silicon power devices have dominated power electronics due to their excellent starting material quality, ease of fabrication, low-cost volume production, and proven reliability. However, they’re approaching their operational limits primarily due to their relatively low bandgap and critical electric field that results in high conduction and switching losses, and poor high-temperature performance. So what can we do? Well, let’s talk about the favorable WBG material properties, their volume application opportunities, and last but not least let's highlight the respective competitive advantages of SiC and GaN.

You will additionally learn about:
  • the lateral and vertical power device configurations that will be analyzed in the context of bidirectional switching
  • specific applications and needs for bidirectional switches
  • key topologies, enabled by bidirectional switches
  • PowerAmerica’s work to accelerate WBG power electronics commercialization
About Dr. Veliadis: Dr. Victor Veliadis is Executive Director and CTO of PowerAmerica, a WBG semiconductor power electronics consortium. At PowerAmerica, he has managed a budget of $146 million that he strategically allocated to 200 industrial and University projects to accelerate WBG semiconductor clean energy manufacturing, workforce development, and job creation. His PowerAmerica educational activities have trained 410 University FTE students in applied WBG projects, and engaged 4100 attendees in tutorials, short courses, and webinars. Dr. Veliadis is an ECE Professor at NCSU and an IEEE Fellow and EDS Distinguished Lecturer. He has 27 issued U.S. patents, 6 book chapters, and over 125 peer-reviewed publications. Prior to entering academia and taking an executive position at Power America in 2016, Dr. Veliadis spent 21 years in the semiconductor industry where his work included design, fabrication, and testing of SiC devices, GaN devices for military radar amplifiers, and financial and operations management of a commercial semiconductor fab. He has a Ph.D. degree in Electrical Engineering from John Hopkins University (1995).

[paper] Special Topic on Materials and Devices for 5G Electronics

Nathan D. Orloff1, Rick Ubic2, and Michael Lanagan3
Special topic on materials and devices for 5G electronics
Appl. Phys. Lett. 120, 060402 (2022); 
DOI: 10.1063/5.0079175
1 NIST, Colorado, USA

3 Penn State University, Pennsylvania, USA

Abstract: Next generation communications are inspiring entirely new applications in education, healthcare, and transportation. These applications are only possible because of improvements in latency, data rates, and connectivity in the latest generation. Behind these improvements are new materials and devices that operate at much higher frequencies than ever before, a trend that is likely to continue. Beyond these exciting applications, higher frequency millimeter waves (mmWaves) may also address a growing problem with capacity. Today, most capacity problems occur when large numbers of wireless connections or applications access the network at the same time at any single location. As wireless internet connections far surpass wired connections and wireless data usage has grown exponentially for more than 10 years,3 many believe that capacity problems will spread without access to new bandwidth.

[PhD] Printed Inorganic Materials Electronics

Circuit Design and Compact Modeling in Printed Electronics Based on Inorganic Materials
PhD Dissertation
Gabriel Cadilha Marques
Veröffentlicht am 30.04.2020
DOI: 10.5445/IR/1000118801

Abstract - The goal of this thesis is therefore to develop an inorganic printed electronics technology with corresponding modeling methodologies to capture device behavior for industry standard circuit simulators as well as circuit designs as building blocks for future applications. To reduce the high supply voltage requirements (~5V) in PE, alternative gating approaches for FETs are considered. One approach is to replace the dielectric with an electrolyte. Due to the formation of a Helmholtz double layer (HDL), a FET with a high gate-capacitance (~5 μFcm-2) is expected, reducing the voltage requirements to ~1V. By combining the indium oxide channel with the electrolyte-gating approach, high performance devices with low voltage requirements are available in PE.
