Abstract:
A device including a gate stack over a semiconductor substrate having a pair of spacers abutting sidewalls of the gate stack. A recess is formed in the semiconductor substrate adjacent the gate stack. The recess has a first profile having substantially vertical sidewalls and a second profile contiguous with and below the first profile. The first and second profiles provide a bottle-neck shaped profile of the recess in the semiconductor substrate, the second profile having a greater width within the semiconductor substrate than the first profile. The recess is filled with a semiconductor material. A pair of spacers are disposed overly the semiconductor substrate adjacent the recess.

Claim (Index 15):
A device, comprising:\n a first gate stack and a second gate stack disposed over a semiconductor substrate; a first spacer element comprising at least one dielectric material, wherein the first spacer element has a first edge abutting a sidewall of the first gate stack and a second edge, opposing the first edge, wherein a surface of the semiconductor substrate interfaces the first spacer element from the first edge to the second edge; and a recess in the semiconductor substrate between the first and second gate stacks, wherein the recess has a diamond-like shape defined by:\n a first portion of a first sidewall extending downward from the surface of the semiconductor substrate and a first portion of a second sidewall opposing the first portion of the first sidewall, a first width defined between the first portions of the first and second sidewalls; \n a second portion of the first sidewall contiguous with the first portion of the first sidewall and extending under the first spacer element abutting the first gate stack and a second portion of the second sidewall contiguous with the first portion of the second sidewall and extending under another spacer element abutting the second gate stack, the second portion of the second sidewall opposing the second portion of the first sidewall, wherein a second width is defined by ends of the second portions of the second sidewalls, the second width being greater than the first width; \n \u2003a third portion of the first sidewall contiguous with the second portion of the first sidewall and a third portion of the second sidewall contiguous with the second portion of the second sidewall, the third portions of the first and second sidewalls defining a width of the recess less than the second width.
