Mechanisms for forming ultra shallow junction |
摘要 |
A method of making a semiconductor device includes forming a fin structure over a substrate. The method further includes performing a plasma doping process on the fin structure. Performing the plasma doping process includes implanting plasma ions into the fin structures at a plurality of implant angles, and the plurality of implant angles has an angular distribution and at least one highest angle frequency value. |
