Abstract :
Radiation tests on SIMOX MOSFETs were conducted with a 5 V bias applied to the drain during irradiation. This resulted in a non-uniform defect distribution along the channel, with the interface region near the drain more heavily damaged. The generated defects were mainly hole traps in the buried oxide and fast states at the front interface. Multiple implantation and capless annealing appear to improve the radiation hardness of SIMOX MOSFETs
