Abstract:
A method of forming a semiconductor device includes receiving a substrate with a plurality of gate structures; forming spacers on sidewalls of the gate structures; evaluating a pitch variation to the gate structures; determining an etch recipe according to the pitch variation; performing an etch process to source/drain regions associated with the gate structures using the etch recipe, thereby forming source/drain recesses with respective depths; and performing an epitaxy growth to form source/drain features in the source/drain recesses using a semiconductor material.

Claim (Index 4):
The device of  claim 1 , further comprising a sidewall spacer disposed along a sidewall of the first gate stack, and\n wherein the first source/drain feature directly interfaces with the sidewall spacer.
