**Abstract:**

Dark Count Rate (DCR) in Single-Photon Avalanche Diodes (SPAD) in Complementary Metal-Oxide Semiconductor technology is characterized and analyzed with a comprehensive simulation methodology. Based on a series of measurements of SPAD with various architectures, on an extended range of voltages and temperatures, the DCR measurements are correlated to the spatial localization of traps within the device and their parameters. To this aim, process and electrical simulations using Technology Computer-Aided Design (TCAD) tools are combined with an in-house McIntyre solver to compute the breakdown probability (Pt). The traps are accounted for using thermal SRH carrier generation-recombination mechanism which is coupled with the position-dependent breakdown probability. This rigorous methodology makes it possible to directly compare with DCR measurements, since only generated carriers with a non-negligible avalanche probability are considered.

It is our great pleasure to invite you to attend the 26th International Workshop on Rare Earth and Future Permanent Magnets and Their Applications (REPM2021) which will be held virtually on June 7-10, 2021. Please note, this is an updated schedule due to COVID-19 travel restrictions which forced us to postpone the conference from summer of 2020. The REPM workshop takes place every two years and is the premier conference on permanent magnets covering a wide range of topics including:

* Rare earth magnets
* Rare earth-free magnets
* Raw materials, mining and recycling
* Advanced synthesis, processing and characterization techniques
* Theoretical modeling of coercivity
* Fundamental properties of advanced magnetic materials
* Thin film magnets
* Applications of permanent magnets

***Workshop***
The workshop will be chaired by Professor George C. Hadjipanayis, University of Delaware, Newark, DE and Dr. Jinfang Liu, President & COO of Electron Energy Corporation, Landisville, PA.
The objectives of the workshop are to bring together engineers and scientists who work on permanent magnets and their applications to present their latest results and exchange ideas on a wide range of relevant topics including resources, raw materials, recycling, processing, fundamental and hard magnetic properties and applications of rare earth and future magnets.

**Abstract:**

In this paper, a 4.3e- RMS low noise 4.6μm Time-of-Flight pixel based on charge domain with kTC noise removal is proposed to enhance the depth camera image quality. The pixel takes advantages of 6μm gradually doped epitaxial layer for 88.5% demodulation contrast at 200MHz and 18.5% QE at 940nm. Buried channel transfer gates are used to enable low capacitive switching and allowing best-in-class 1.4μW/pixel power consumption at 200MHz. The pixel is fully isolated due to deep trench isolation and pixel bulk is biased at several hundreds of mV for ultimate low power Time-of-Flight sensor and system. The paper describes the design of 0.54Mpix camera (672 x 804 pixels) implementing demodulation circuits robust against EMI and multi-devices interferences. The performance of an indirect Time-of-Flight system is demonstrated with 1.0% depth noise under 40kLux at 30fps.

**Abstract:**

We will present major advances in Time of Flight image sensors for consumer applications. Several innovative elements integrated into a 130nm front side illumination CMOS node reveal superior sensor performance so far only attributed to much more complex backside illumination technologies. The gate controlled pixels comprising deep trenches, buried mirrors and integrated prisms, reveal high quantum efficiency and modulation transfer function close to the physical pixel size. In-pixel common mode suppression prevents saturation even under backlight conditions. The comprehensive System on Chip integrates high speed ADCs, a flexible phase shifter, as well as current monitoring for laser safety.

**Abstract:**

An analytical model for back bias capability including interface traps, quantum confinement, short channel effects is developed, which is in excellent agreement with TCAD simulations and measurements. The derived expressions facilitate the accurate assessment of interface trap impact on variability and also benefit the configuration of dynamics back bias for aging compensation, thereby fully leveraging the UTBB FDSOI technology.

**Abstract:**

In this study, a consistent analytical chargebased model for the bias-dependent variability of the drain current of organic thin-film transistors is presented. The proposed model combines both charge-carrier-numberfluctuation effects and correlated-mobility-fluctuation effects to predict the drain-current variation and is verified using experimental data acquired from a statistical population of organic transistors with various channel dimensions, fabricated on flexible polymeric substrates in the coplanar or the staggered device architecture.

**Abstract:**

A charge-based macromodel for small-signal ac and transient analyses of organic thin-ﬁlm transistors (TFTs) is presented. Due to the comparatively small charge- carrier mobility in organic TFTs, the dynamic behavior of the gate-ﬁeld-induced carrier channel is greatly affected by the frequency of the applied gate–source and drain–source voltages. The model presented here is, therefore, based on the transmission-line model and shown to reproduce the results of frequency-dependent admittance measurements and numerical simulations of the transient switching behavior of organic TFTs fabricated in the staggered architecture with good accuracy. The model has been implemented in the hardware description language Verilog-A.

Multi-channel potentiostats are required for monitoring electrochemical processes in a time- and cost- efficient manner. State-of-the-art PCB potentiostats suffer from limited performance. Existing integrated CMOS potentiostats enable large number of parallel sensing channels, yet are still limited in the number of parallel stimulation channels and their bandwidth. The presented 40nm CMOS potentiostat chip overcomes this bottleneck with 96 individually controllable channels with 125dB current dynamic range and up to 150kHz bandwidth using an on-chip digital feedback controller. The chip supports both on-chip and off-chip electrodes allowing flexible electrode dimensions.

This keynote is describing the evolution of Artificial Intelligence (AI) adoption to the Edge for maximizing Data processing at the User experience level to treat as much as possible data analysis without saturating Internet traffic and Cloud data centers. Evolution of Neural Network (NN) computing through progressive usage of In Memory Computing (IMC) is also described. A few examples of Artificial Intelligence at the Edge are also commented. We then describe how at ST, we address competitive solutions for Edge AI thanks to differentiated FD-SOI CMOS technology, Phase Change Memory (PCM) embedded memory integration and advanced NN and IMC design solutions.
