Abstract:
Disclosed are integrated circuit (IC) structures and formation methods. In the methods, a gate with a sacrificial gate cap and a sacrificial gate sidewall spacer is formed on a channel region. The cap and sidewall spacer are removed, creating a cavity with a lower portion between the sidewalls of the gate and adjacent metal plugs and with an upper portion above the lower portion and the gate. A first dielectric layer is deposited, forming an air-gap in the lower portion and lining the upper portion. A second dielectric layer is deposited, filling the upper portion. During formation of a gate contact opening (optionally over an active region), the second dielectric layer is removed and the first dielectric layer is anisotropically etched, thereby exposing the gate and creating a dielectric spacer with a lower air-gap segment and an upper solid segment. Metal deposited into the opening forms the gate contact.

Claim (Index 10):
The integrated circuit structure of  claim 8 , the dielectric spacer further comprising an additional segment between the semiconductor body and the lower air-gap segment, wherein the additional segment and the upper solid segment comprise two different dielectric materials.
