Claim:
1. A semiconductor structure comprising: at least one semiconductor nanowire pair located over a substrate, wherein each of said at least one semiconductor nanowire pair includes: a semiconductor material source structure having a rectangular vertical cross-sectional shape adjoined to said lower semiconductor nanowire and said upper semiconductor nanowire; a semiconductor material drain structure having another rectangular vertical cross-sectional shape adjoined to said lower semiconductor nanowire and said upper semiconductor nanowire; a source cap material portion located on said semiconductor material source structure; a drain cap material portion located on said semiconductor material drain structure, said source cap material portion is spaced apart from said drain cap material portion; a raised source region in direct physical contact with a sidewall surface of each of said semiconductor material source structure and said source cap material portion and extending onto a topmost surface of said source cap material portion; and a raised drain region in direct physical contact with a sidewall surface of each of said semiconductor material drain structure and said drain cap material portion and extending onto a topmost surface of said drain cap material portion.
