Upcoming Seminar on Power Semiconductor Evaluation Techniques

CMC Research is excited to announce a live webinar titled "Next-Generation Power Semiconductors and Power Devices Crystal Defect Evaluation Techniques and Trends," scheduled for September 29, 2025, from 1:30 PM to 4:30 PM (JST). This seminar will be hosted by Prof. Yao Yongzhao, a leading figure in semiconductor research from Mie University, focusing on the latest advancements in the evaluation of crystal defects in wide-bandgap semiconductors.

Why Attend?

This seminar is crucial for researchers and engineers involved in semiconductor crystal defect evaluation. It aims to provide participants with comprehensive knowledge regarding:

• - Crystal structures
• - Types of defects within crystals
• - Methods for evaluating these defects
• - The impact of defects on device performance

With the rapid developments in power devices using wide-bandgap semiconductors such as 4H-SiC, GaN, and β-Ga2O3, understanding defect analysis has become increasingly vital. These materials exhibit superior performance attributes, including high power density and stability at elevated temperatures. However, challenges arise due to the high density of lattice defects, which can significantly impair device reliability. By identifying killer defects through accurate defect distribution and type analysis, attendees will learn how to mitigate these issues, ensuring optimal device reliability and performance.

Seminar Agenda

The following topics will be covered during the webinar:
1. Introduction to Wide-Bandgap Semiconductors and Their Defects
- Understanding power device structures
- Significance of defect evaluation methods
2. Exploration of Defect Evaluation Techniques
