Claim Text:
1. A semiconductor structure comprising: a first gate structure straddling a first semiconductor material portion on a substrate; a second gate structure straddling a second semiconductor material portion on said substrate; a first gate spacer laterally surrounding said first gate structure; a second gate spacer laterally surrounding said second gate structure; first raised active regions located on said first semiconductor material portion; second raised active regions located on said second semiconductor material portion; a dielectric stack contacting said first raised active regions and said first gate structure, and not in physical contact with said second raised active regions; and a material layer including a dielectric material and in physical contact with said dielectric stack and surfaces of said second raised active regions, wherein all outer sidewalls of said first gate spacer are in contact with one of said dielectric stack and said first raised active regions.
