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 1):
A device comprising:\n a first fin structure and a second fin structure disposed over a substrate; a first gate stack disposed over the first fin structure and a second gate stack disposed over the second fin structure; a first source/drain feature disposed in the substrate adjacent the first gate stack, the first source/drain feature extending to a first depth within the substrate; and a second source/drain feature disposed in the substrate adjacent the second gate stack, the second source/drain feature extending to a second depth within the substrate that is less than the first depth.
