Abstract
Avalanche hole injection into a buried oxide formed by ion implantation is successfully used to determine the effective hole trap densities and the corresponding capture cross-sections. The material used for this study was a standard commercial wafer, fabricated by the separation-by-implantation-of-oxygen (SIMOX) process. Analysis of the mid-gap voltage shift in the high frequency capacitance-voltage curve against injected charge reveals the existence of three distinct hole traps with cross-sections about 10 times larger than those found for thermal oxides
