Abstract:
Methods are disclosed herein for fabricating semiconductor devices having shared source/drain contacts. An exemplary semiconductor device includes a high-k/metal gate stack disposed over a substrate. The high-k/metal gate stack is disposed between a first source/drain feature and a second source/drain feature. A first spacer set is disposed along sidewalls of the high-k/metal gate stack. A first interlevel dielectric (ILD) layer is disposed over the substrate. Upper portions of the first spacer set that extend above the first ILD layer have a tapered width. A second spacer set is disposed on the upper portions of the first spacer set and over the first ILD layer. A second ILD layer is disposed over the first ILD layer. A contact feature extends through the second ILD layer to the first source/drain feature and the second source/drain feature. The contact feature spans uninterrupted between the first source/drain feature and the second source/drain feature.

Claim (Index 5):
The semiconductor device of  claim 4 , wherein the contact feature further physically contacts one spacer of the first spacer set, one spacer of the third spacer set, one spacer of the fourth spacer set, and one spacer of the sixth spacer set.
