摘要:
The present disclosure relates generally to doping for conductive features in a semiconductor device. In an example, a structure includes an active region of a transistor. The active region includes a source/drain region, and the source/drain region is defined at least in part by a first dopant having a first dopant concentration. The source/drain region further includes a second dopant with a concentration profile having a consistent concentration from a surface of the source/drain region into a depth of the source/drain region. The consistent concentration is greater than the first dopant concentration. The structure further includes a conductive feature contacting the source/drain region at the surface of the source/drain region.
