Abstract:
Metal gate cutting techniques for fin-like field effect transistors (FinFETs) are disclosed herein. An exemplary method includes receiving an integrated circuit (IC) device structure that includes a substrate, one or more fins disposed over the substrate, a plurality of gate structures disposed over the fins, a dielectric layer disposed between and adjacent to the gate structures, and a patterning layer disposed over the gate structures. The gate structures traverses the fins and includes first and second gate structures. The method further includes: forming an opening in the patterning layer to expose a portion of the first gate structure, a portion of the second gate structure, and a portion of the dielectric layer; and removing the exposed portion of the first gate structure, the exposed portion of the second gate structure, and the exposed portion of the dielectric layer.

Claim (Index 12):
The method of  claim 11 , wherein the first and second metal gate structures are formed by replacing dummy gate structures, wherein the first and second metal gate structures include metal gates and spacers disposed on sidewall surfaces of the metal gates, wherein simultaneously etching the exposed portion of the first metal gate structure and the exposed portion of the second metal gate structure comprises simultaneously etching the metal gates and the spacers.
