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 15):
The semiconductor device of  claim 9 , wherein the first gate stack, the second gate stack, and the third gate stack each include a respective metal gate layer disposed over a respective high-k gate dielectric layer.
