GaN Powers Up in AI, Robotics, and Our Lives

Author: All About Circuits February 18, 2025 Duration: 51:41

In this fascinating interview, Alex Lidow discusses his early exposure to semiconductors through his father and grandfather, who founded International Rectifier. Initially pursuing aeronautical engineering at Caltech, he shifted to solid-state physics, igniting a lifelong career. He shares his role in developing HexFETs, a groundbreaking transistor technology, highlighting the creativity and persistence required for innovation.

After being unexpectedly dismissed from International Rectifier, Alex founded EPC to focus on GaN technology. He details GaN's superior properties, such as high efficiency and robustness, which make it a transformative alternative to silicon in power devices.

Despite early struggles with manufacturing yields, persistence led to breakthroughs that enabled GaN's application in LiDAR, space electronics, and fast chargers. Alex reflects on how mistakes foster breakthroughs and stresses the importance of education to help engineers adopt GaN technology.

Looking ahead, Alex expresses excitement about emerging applications, such as humanoid robots, where GaN's integration in motors, AI, and LiDAR could revolutionize industries. His advice to aspiring innovators is to embrace challenges and persist through the highs and lows of invention.
