STMicroelectronics has developed a new generation of 40nm CMOS technology with embedded Non Volatile Memory targeted to support advanced Microcontrollers platforms. The presentation will briefly describe the very first implementation done with a standard Flash memory with high density but limited granularity (sector erase). We’ll then detail a second step, with a new NVM cell (eSTMTM) integrating a vertical select transistor to offer density similar to standard flash, but better erase control and granularity, that have been integrated in different IP blocks to suit MCU requirements. A latest step, will then be explained, showing further area reduction, as well as some perspective for generation ahead. From a circuit point of view, General Purpose MCUs done, with the initial technology, include a dual core for optimized performance and pass the 1000 DMips mark, while a derived version, using the optimized eSTMTM NVM cell, offer a 30% power consumption reduction. For secure MCU, 3 main applications have been targeted using the 40nm eSTMTM technology: circuit for contactless payment cards with biometry, harvesting enough energy to support a finger print sensor and verification, a circuit for embedded SIM with large NVM to allow high security loading and storage of virtual SIM cards and finally a combined embedded Secure Element and NFC controller (using the smallest eSTMTM cell) to support contactless applications in mobile phone such as payment, access control… Market for each applications represents hundreds of millions of circuits every year requiring robust, reliable and cost effective eNVM technologies.

**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!

The aim of this paper is to present the 3D-sequential integration and its main prospective application sectors. The presentation will also give a synoptic view of all the key enabling process steps required to build high performance Si CMOS integrated by 3D-sequential with thermal budget preserving the integrity of active devices and interconnects and will sketch a status and prospect on current low temperature device performanc

3D sequential integration: opportunities and challenges

Design of 3D ICs is mainly done in separated design environments for each tier, assuming that communication channels between tiers are user-defined and fixed at the beginning of the design process1,2. Suitable for 3D stacking based on TSV or Hybrid Bonding technologies because of the low granularity of these 3D interconnect elements, this methodology becomes more difficult to apply to 3D sequential technologies once trying to integrate Monolithic Inter-tier Vias (MIV) with higher density (around 1.108 vias per mm2). In this paper, we describe a methodology to create a unified design environment, which includes several technologies attached to different tiers. Main advantage of this methodology is that designing a 3D circuit may no more require several design environments, thus simplifying simulations, verifications and layout finishing.

Merging PDKs to build a multi-process multi-tier 3D design environment

A 14-bits cyclic ADC is implemented in two-tier 3D sequential integration
(3DSI) multi-process technology. The ADC specifications are intended
for the daughter-payloads of the investigation of cusp irregularities (ICI) sounding
rocket series, i.e. small sensor platforms that are ejected in-flight to measure
plasma electron density in a cloud around the rocket. The two 3DSI processes
used are a 65nm SOI technology with 28nm shrink transistors in the top tier
and 28nm FDSOI as the bottom tier. This work aims to explore architectures
in a high-density interconnect 3D sequential integration process for area and
power reduction, exploiting fine-grained transistor placement as well as device
parameter optimization having the choice of two different CMOS technologies
for each individual device.

This presentations deals with innovative approaches of 3D stacking Image sensors. Comparisons with conventionnal 3D vs sequential stacking is described.

Innovative Fine Pitch Architectures dedicated to Image Sensors: from Hybrid Bonding to 3D Sequential integration

The presentation is related to the EU-funded 3D-MUSE project where an extra layer of transistors is produced on top of a standard CMOS technology. Some readout circuits for radiation will be presented as well as how they can make use of several transistor layers. Examples are a multi-channel PMT, a thermal image sensor and a light radar. A simple TDC (Time to Digital Converter) will also be presented.

3D Integrated Circuits for Radiation Sensor Readout

In an industry wide consensus perpendicular spin-transfer-torque magnetic random-access memory (pSTT-MRAM) has matured to the memory of choice for replacing embedded FLASH solutions in the 2X nm technology nodes and beyond. However, especially this first entry point as a replacement for solder-reflow-capable eFLASH implies stringent requirements when it comes to high temperature data storage capabilities. In highly scaled pSTT-MRAM this demanding non-volatility can only be achieved by advanced free layer engineering. This energy barrier modulation needs to be carefully balanced in the boundary conditions of power consumption and endurance requirements. Sustaining and predicting this balance already at film-level or during patterning will be highly rewarding for the reliable manufacturing of this new technology. Here we present an early view on film-level and post-patterning magnetic metrology for embedded pSTT-MRAM.

Magnetic Metrology on Fully Integrated Embedded STT-MRAM

The architectural innovations of a new FPGA is presented.
The programmable Element, the routing structure and innovative switchboxes are explaned.

Novel Architecture for European FPGA

The modern world witnesses an ever-growing variety of consumer, home, automotive and industrial devices with network connectivity. 
Security is a crucial aspect in such systems and stakeholders will confirm that security constantly evolving. 
Therefore, NXP is very much involved in developing resilient, secure and trustworthy products that are a crucial building block for European data sovereignty. 
This results in the foundation that our customers use to build secure products.

In this presentation we will highlight the contributions of NXP Semiconductors Austria in the scope of IPCEI. 
This ranges from implementation security for high security products like Roots of Trust, 
over safe and secure battery management system for the green revolution as well as innovative 
application of technology for security use cases like Ultra-Wide-Band (UWB) radio for car access.

A connected world – Why security matters

5G standards effective deployment drives considerable technology challenges and implications on mobile devices design and requires innovative solutions to solve them. 
At the RF Front End Modules (FEM) level, the usage of new frequency bands, the complex use of the frequency bands (Carrier Aggregation, MIMO, QAM) and the coexistence with 4G networks are challenging the limits of existing acoustic filter technologies. 
A promising approach combining a thin single crystal LiTaO3 layer bonded on a Silicon substrate - so called Piezo On Insulator (POI) – together with the existing Surface Acoustic Wave (SAW) filter technology, enables to take advantage of guided waves that do not suffer from any radiation leakage. This SAW on POI approach will extend the use of the existing SAW technologies for higher performance integrated acoustic devices.
Triggered by the 5G filter market demand, the Smart CutTM technology has enabled high performance POI substrates supply chain in volume manufacturing, and paves the way to new design approaches for many applications beyond the Smartphone market.


Smart CutTM Piezo On Insulator (POI) substrates for high performance integrated acoustic devices

The IPCEI program at GF includes innovation along all technology readiness levels (TRLs). One example for very low TRL is the Reconficurable FET based on Schottky Barriers, close to 22FDX-processing. It enables camouflaging circuits for security applications, by e.g. providing NAND or NOR type cells, that can not be identified by reverse engineering. Another example is the development of a mmWave-variant of 22FDX allowing for operation frequencies typically in the 28-80 GHz regime, but also ranging up to 140 GHz. Characterisation of devices up to 3-4 times the operational frequency, a prerequisite for operation of the devices at these frequencies and showcases in the GHz regime for auto-Radar, 5 G and imaging radar are shown. These are just two examples, how the energy efficient 22FDX-technology at GF is enrichened by specialized variants and applications-specific- features.
