Improvement of breakdown voltage and off-state leakage in Ge-implanted SOI n-MOSFETs

This work demonstrates a well-controlled technique of channel defect engineering, by implanting Ge into the SOI device channel to act as a minority carrier lifetime killer in order to reduce the parasitic bipolar effect and thus improve the source-to-drain breakdown voltage. The Ge-implant also serves the dual purpose of creating Si structural defects in the back interface region which reduce the back channel off-state leakage.<
