Processing of GaN vertical devices: Static Induction Transistors

In this presentation we will see how vertical GaN devices have made progress over the last decade. Beyond CAVET and MOSFET, we are observing very interesting device performances in more simple geometry device like Static Induction transistor (SIT). We will focus on the recent advancement made in SIT development. Lack of avalanche continues to stay as an issue that although observed and reported in GaN devices, is not yet a routine phenomenon. We will discuss key issues in device processing that we have to overcome to enable a viable path into next-generation power electronics applications.
