Abstract:
A process for manufacturing a semiconductor device and the resulting structure are presented. In an embodiment a source/drain region is grown. Once grown, the source/drain region is reshaped in order to remove facets. The reshaping may be performed using an etching process whereby a lateral etch rate of the source/drain region is larger than a vertical etch rate of the source/drain region.
