Abstract

The gettering efficiency process in platinum doped fast rectifiers was studied by transmission electron microscopy. We have observed orthorhombic PtSi-(monocrystalline) precipitates in n+ gettering region with the following epitaxial relationship: (011)PtSi//{110}Si with [010]PtSi//〈112〉Si. This precipitation can be related to the presence of orthorhombic SiP particles induced by highly phosphorus doping, without any dislocations around them.
