Patent ID: 8828832

Claim:
A method comprising: forming a gate structure on a surface of a semiconductor substrate; forming a sidewall spacer on the gate structure; forming a recess within the semiconductor substrate adjacent the sidewall spacer; modifying the recess within the semiconductor substrate such that the modified recess has a first portion that extends from the surface of the semiconductor substrate and a second portion that extends from the first portion at a first angle ranging from about 50° to about 70° and a third portion that extends from the surface of the semiconductor substrate and a fourth portion that extends from the third portion at a second angle ranging from about 50° to about 70°, the second portion directly opposing the fourth portion, wherein the first and second angles are measured with respect to an axis that is parallel to the surface of the substrate, wherein the first portion is aligned with an outer edge of the sidewall spacer, wherein the outer edge of the sidewall spacer is further away from the gate structure than an inner edge of the sidewall spacer; and depositing a semiconductor material into the modified recess, wherein the semiconductor material is different from the semiconductor substrate.
