  • Publication number: 20200328106
    Abstract: Gate cutting techniques for integrated circuit devices, particularly for fin-like field effect transistor devices, are disclosed herein. An exemplary method includes receiving an integrated circuit device that includes a gate structure and performing a gate cut process to separate the gate structure into a first gate structure and a second gate structure. The gate cut process includes selectively removing a portion of the gate structure, such that a residual gate dielectric layer extends between the first gate structure and the second gate structure. In some implementations, the residual gate dielectric includes a high-k dielectric material. The method further includes forming a gate isolation region between the first gate structure and the second gate structure.
