Bipolar switching between accumulation and inversion can result in an unexpected threshold voltage drift in SiC MOSFETs. This gate switching instability (GSI) is significantly larger than what is known for bias temperature instability (BTI). Based on the similarity to charge pumping experiments, we develop a comprehensive physical model for GSI based on recombination enhanced defect reactions, derive a closed form analytical solution, and finally validate the model against detailed experimental data.

**Abstract:**

Silicon and its native oxide SiO 2 are the most commonly used materials in semiconductor device technology. After decades of research in this field, details of the initial oxidation and the subsequent O migration and amorphization are still a subject of interest. In this paper, we present a multiscale modeling approach to investigate the oxidation process of a Si(100) surface. Starting from the adsorption and dissociation of single O 2 molecules, we further extended our investigations towards the initial oxidation of the first Si layer and subse- quent O migration. Finally, we construct a realistic model of a Si/SiO 2 interface consisting of around 5000 atoms. The employed simulation techniques used in this study range from density functional theory (DFT) to density functional based tight binding (DFTB) to classical molecular dynamics (MD).

**Abstract:**

A ML based framework is presented to predict the formation and structure of defect in amorphous structures, aiming at reducing the computational costs which these studies require. The framework is applied to the prediction of hydroxyl E\' center defects in amorphous silicon dioxide. The results demonstrate a competitive level of accuracy, while being computationally inexpensive, when compared to DFT.

**Abstract:**

It is well established that oxide defects are a major threat concerning the reliability of electronic devices. Point defects like the oxygen vacancy and hydrogen related defects like the hydrogen bridge and the hydroxyl-E\' center can trap charges from the Si substrate during operation. Here we present a statistical study of parameters by analyzing 144 defects of each type in amorphous SiO2 . We use density functional theory in conjunction with a hybrid functional to provide a large and accurate dataset of defect parameters such as the relaxation energy or the charge transition level and link them to bias temperature instability in nMOSFET devices.

**IRPS 2024 General Chair Welcome Message**

On behalf of the Management Committee of the IEEE International Reliability Physics Symposium (IRPS) and the IRPS Board of Directors, it gives me great pleasure to extend a warm welcome to all who are planning to attend the IRPS 2024, scheduled to take place from April 14-18, 2024, in Dallas, TX. 
Over its 62-year history, IRPS has solidified its position as the premiere conference for engineers and scientists to present new and original work in the field of microelectronics reliability. Drawing participants from the United States, Europe, Asia, and other parts of the world, IRPS aims to deepen our understanding of reliability of semiconductor devices, integrated circuits, and microelectronic assemblies through an improved understanding of both the physics of failure as well as the application environment. IRPS offers diverse opportunities for attendees to enhance their knowledge and understanding of all aspects of microelectronics reliability. It is also an outstanding chance to meet and network with reliability colleagues from around the world.

The IRPS 2024 technical activities will begin with two days of a total of twenty tutorial sessions covering a broad spectrum of emerging reliability topics beyond CMOS device, circuit and system reliability. These sessions are devoted to both newcomers as well as experts. Three reliability Year in Review (YIR) talks focusing on neuromorphic computing, dielectric breakdown in leading edge devices, and GaN technology will be provided on Monday after the tutorials.

The IRPS 2024 technical program will feature four distinguished keynote talks in the plenary sessions delivered by Prof. Shinichi Takagi from The University of Tokyo and Dr. Su Jin Ahn from Samsung on Tuesday, Dr. Rajeev Malik from IBM on Wednesday, and Dr. Sameer Pendharkar from Texas Instruments on Thursday. The technical program, organized into three parallel tracks, consists of contributed and seventeen invited papers from leaders in industry and academia. Additionally, two invited talks by recipients of paper awards from our sister conferences, European Symposium on Reliability of Electron Device Failure Physics and Analysis (ESREF) 2023 and the International Integrated Reliability Workshop (IIRW) 2023, will be given in the technical program. 

Tuesday evening will host ten workshops, offering an opportunity for in-depth, face-to-face discussions on emerging reliability challenges, including the three IRPS 2024 focus topics. A poster session will be held in the Austin Ranch outside the symposium building on Wednesday evening. Both events are sure to be lively. The IRPS 2024 and the International ESD Workshop (IEW) will be co-hosted with IEW registrants participating in both IRPS and IEW programs.

The IRPS 2024 will adopt a hybrid conference style, allowing virtual access to live oral presentations hosted by the Underline. Real-time streaming of all technical events (excluding Workshops and Posters) will be available in the US Central Timezone, providing virtual attendees with Q&A opportunities. For those virtual attendees who cannot watch the live presentations, the material will be available on demand to all attendees after the symposium. All authors will be presenting in person.

Finally, I would like to extend my extreme gratitude to our patrons, exhibitors, and all participants for their invaluable support, which makes IRPS successful. 

Please enjoy the IRPS 2024!
