Abstract:
A method includes forming a fin extending above an isolation region. A sacrificial gate stack having a first sidewall and a second sidewall opposite the first sidewall is formed over the fin. A first spacer is formed on the first sidewall of the sacrificial gate stack. A second spacer is formed on the second sidewall of the sacrificial gate stack. A patterned mask having an opening therein is formed over the sacrificial gate stack, the first spacer and the second spacer. The patterned mask extends along a top surface and a sidewall of the first spacer. The second spacer is exposed through the opening in the patterned mask. The fin is patterned using the patterned mask, the sacrificial gate stack, the first spacer and the second spacer as a combined mask to form a recess in the fin. A source/drain region is epitaxially grown in the recess.

Claim (Index 15):
A device comprising:\n a fin over a substrate; a gate stack along sidewalls and over a top surface of a channel region of the fin, the gate stack having a first sidewall and a second sidewall opposite to the second sidewall; a first gate spacer structure along the first sidewall of the gate stack, the first gate spacer structure comprising a first gate spacer, a first portion of the first gate spacer extending along the first sidewall of the gate stack, a second portion of the first gate spacer extending laterally away from the first sidewall of the gate stack and over the top surface of the fin; a second gate spacer structure along the second sidewall of the gate stack, the second gate spacer structure comprising a second gate spacer, a first portion of the second gate spacer extending along the second sidewall of the gate stack, a second portion of the second gate spacer extending laterally away from the second sidewall of the gate stack and over the top surface of the fin, a width of the second portion of the second gate spacer being less than a width of the second portion of the first gate spacer; a first epitaxial region adjacent the first gate spacer structure; and a second epitaxial region adjacent the second gate spacer structure.
