Abstract
A novel process for the isolation of AlGaN/GaN HFETs is reported, utilising co-implantation of phosphorus and He ions. After implantation the material sheet resistance is > 108 Ω/□, even at temperatures as high as 200°C. The high resistance is maintained for high temperature anneals > 700°C. HFETs fabricated with this procedure exhibit good characteristics.Keywords
