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 5):
The device of  claim 1 , wherein the third spacer and the fourth spacer comprise different materials.
