**Abstract:**

By alleviating the multiply operation with simple XNOR, Binary Neural Networks seem an appealing solution to overcome the von Neumann bottleneck. In this context, we demonstrate experimentally the robustness of XNOR operation, in memory, based on resistive bridge (2T2R cell), with complementary coding of weights and input neuronal activations. Based on these measurements, we validate, through an extensive set of Monte Carlo simulations, that this approach is suitable for large neurons with very low error rate. Based on circuit results, Neural network simulations shows a very limited accuracy degradation on the MNIST task (0.07%) and CIFAR-10 task (0.35%).

**General Chair Welcome Message**

Welcome to IRPS 2022! When the IRPS Management Committee began making plans for Dallas, we recognized the strong desire by the reliability physics community to return to a face-to-face symposium that we last had in Monterey in 2019. But as time progressed, we recognized that travel restrictions were not being lifted as rapidly as we anticipated. Rather than leave out those of you who could not attend in person, we adopted a hybrid format allowing for both remote attendance and remote presentations. This is a first for IRPS and I am confident it will be a success for all.

With this new hybrid format, the symposium will return to the original five-day format with Tutorials and Year in Review on the first two days. The Technical Program, Keynote Talks, Workshops and Poster session will be held on the following three days. All of these (except Workshops and Posters) will be available via real-time streaming in the US Central Time zone with virtual attendees having Q&A access to the presenters. For those virtual attendees who cannot watch the live presentations, the material will be available on demand to all attendees for a month after the symposium with the ability to communicate with the authors.

In 2020, we were planning on co-hosting the International ESD Workshop (IEW) ESD workshop when the COVID-19 pandemic hit. For 2022, IEW will be seamlessly embedded into the IRPS Program and will sponsor three tutorials, an invited talk, two technical sessions and two evening workshops focused on ESD and latch-up. And we continue our
collaboration with our sister conference, European Symposium on Reliability of Electron Devices Failure Physics and Analysis (ESREF) by hosting their Best Paper and the International Integrated Reliability Workshop (IIRW) by hosting their Best Student Paper.

Our primary objective is to maintain the symposium’s leadership role in the reliability physics of microelectronic devices by attracting leading researchers to present their work and providing attendees the best place to access this information. With all the buzz in the media about whether Moore’s Law has hit its limit, IRPS has been promoting expertise developed in silicon-based reliability over the past sixty years and expanding into new material areas. This year, eight of the technical sessions are devoted to reliability in topics outside of traditional silicon, including wide bandgap GaN/SiC, emerging memory and neuromorphic computing. I hope our ability to draw these communities together will accelerate the cross-fertilization of ideas. 

The Technical Program consists of four keynote speakers, twenty-three invited speakers and eighty-seven oral presentations organized in thirty technical sessions on eighteen reliability topics. Over two evenings, there will be ten Workshops and sixty-six Poster presentations that are designed to allow in person attendees and experts to interact
with one another. With eighteen tutorials covering topics ranging from fundamental transistor and memory reliability all the way up to automotive and complex system-level reliability, this year’s symposium provides an excellent learning opportunity for engineers and scientists new to reliability as well as experienced individuals wanting to explore new
areas. The Year in Review, which serves as a summary of research in the past year, will cover 3D packaging, emerging memory and aging aware circuit designs.

Finally, I would like to express my extreme gratitude to our patrons and exhibitors, whose support makes IRPS possible.
And to all of you, our in person and virtual attendees, for supporting this symposium for sixty years!

**Abstract:**

Active rectifier, biomedical implantable devices, coarsefine, delay compensation, wireless power transfer (WPT). This letter presents an active rectiﬁer with SAR-assisted coarse-ﬁne adaptive digital delay compensation technique for biomedical implantable devices. Both on- and off-delays are compensated by adjusting the comparator offset. In order to achieve accurate zero-voltage switching against process, voltage, and temperature variations, a two-step coarse-ﬁne digital tuning method is introduced. The coarse-tuning phase and the ﬁne-tuning phase are controlled by a 7-bit SAR controller and a 3-bit bidirectional counter, respectively. The proposed technique could avoid reverse current and achieve maximum conduction time for power switches. Meanwhile, it is suitable for compensating power switch with large on/off-delay variation.

**Abstract:**

A multichannel impedance-sensing CMOS chip for the readout of non-invasive light detectors in Silicon Photonics is presented. The performance of the lock-in phase-sensitive demodulator is improved thanks to a capacitive feedback transimpedance amplifier (TIA) equipped with an active discharge network, able to keep a DC output offset lower than 3 mV for leakage currents up to 4 nA while injecting a noise lower than 40 fA/sqrt(Hz). The addition of a sensor capacitance compensation system at the input of the chip allows a 30-fold increase of the stimulation amplitude, enabling the tracking of sub-picoSiemens conductance variations on a baseline of few uS, with a bandwidth of 70 Hz. The chip performance opens the way to multipoint monitoring of complex photonic systems, addressing the challenges posed by the growing complexity of these architectures.

**Abstract:**

This paper presents dual-layer proton irradiation profile to improve the thermal stability of high-resistivity substrate formed by low-fluence proton irradiation. Dual-layer irradiation uses targeted irradiation to the Si-SiO2 interface to reduce the fluence required for preventing the formation of conduction layer after annealing. Thermal stability of effective substrate resistivity is evaluated indirectly through inductor Q-factor measurement before and after annealing at 260°C for 1 minute. With the same total fluence, measurement result shows the proposed dual-layer irradiation profile can suppress post-anneal Q-factor degradation from 17% to 1%. The required active devices margin from irradiated area is also reduced by 26%.

**Abstract:**

Shunt admittance of FETs for mm-wave switch applications are investigated, complementing the well-know series elements Ron/Coff. Tese shunt elements can be responsible for significant loss, and devices with the lowest RonCoff may not be the best suited for high-frequency switches. This is demonstrated by comparing 20 nm SLVT and BFMOAT devices from GLOBALFOUNDRIES’ 22FDX® technology. While the SLVT presents an RonCoff metric of 100 fs, it is outperformed by the BFMOAT that has an RonCoff of 160 fs, thanks to reduced parasitic shunt loss. A DC-80 GHz SPDT is measured, showcasing BFMOAT’s excellent characteristics for mm-wave switches, achieving competitive results.

**Abstract:**

The adoption of 5G mmWave is upon us, with major cell phone companies having introduced phones with mmWave capabilities and major US cellphone providers building their infrastructure out. Parts manufactured using Globalfoundries 45RFSOI technology have made significant traction in the infrastructure space. A good part of the success of this technology is based on the excellent high frequency performance of the thin oxide device, the high resistivity substrate and the high voltage support enabled by the use of stacking in SOI technologies. In this paper we introduce a new transistor developed to improve the output power of mmWave power amplifiers (PA). It demonstrates ~ 1.2X increase in maximum voltage, reduced linear mode resistance and ~20% increases in fMAX to >400 GHz

**Abstract:**

This paper presents the first GC-eDRAM in 16nm FinFET technology, featuring a mixed-VT 3T gain-cell structure to minimize the storage node (SN) leakage. The implemented 1 Mbit 3T GC-eDRAM is fully logic-compatible and provides a 2X smaller bitcell size compared to a 6T SRAM with similar design rules, offering the highest density logic-compatible memory cell in 16nm technology. Measurement results demonstrate a 77 μs DRT under a 600mV VDD, which is over 10X longer than previously reported GC-eDRAMs in 28nm technologies. The memory was fully operational at temperatures spanning -40C–125C and under a supply voltage as low as 450mV, providing the lowest measured VDDmin and widest temperature range reported in the literature for GC-eDRAM.

**Abstract:**

An area-efficient inductive coupling interface for a 3-D-stacked high-bandwidth memory is presented. A test chip was fabricated in a 40-nm CMOS technology and 1.5-Gb/s 2.2-pJ/bit communication using a 0.23-V NMOS transmitter and 7-µm multi-layer coils was experimentally confirmed. The low-voltage transmitter reduces power dissipation by 55% in measurement. The proposed 7-µm multi-layer coils improve their mutual inductance by a factor of 4.5 compared with conventional single-layer ones. Using this interface, a memory module consisting of eight 8-µm-thick memory dies and a base die in a 40-nm CMOS process is extrapolated to achieve a 2.3-Tbps/mm2 area efficiency and 6.1-pJ/bit energy efficiency.

**Abstract:**

We proposed 3D-based redundancy scheme for stacked DRAM systems, which enables high productivity with wafer-on-wafer (WOW) technology. Vertically replaceable block scheme, and redundantly added wafer stack(s) are the keys of this technique. Memory bank replacement of vertical combinations is taken into consideration. Random defect yield loss, which is a fundamental barrier for both of the WOW technology and the leading-edge technologies, is dealt with in this study. Evaluation of many layers stacking capability leads to the result, that 3D redundancy technique is applicable even for devices with many layers of stacking. Therefore, this technique makes the WOW technology, as another system scaling enabler.
