Old ideas are best

Our Newsletter Editor, Dr John Grange, smiled when he read recent press reports about a new technique for boosting the performance of high powered GaN devices. In collaboration with Surrey University he worked back in 1980-2 on various inert gas/proton isolation techniques. To be successful, the NCSU team need to overcome the issues surrounding post implant processing and the lifetime/stability/reproducibility of the implant isolation under real device operational conditions. He came to the conclusion that there are better solutions, but he wishes them well.
