  • Publication number: 20240112959
    Abstract: A method of fabricating a device includes forming a dummy gate over a plurality of fins. Thereafter, a first portion of the dummy gate is removed to form a first trench that exposes a first hybrid fin and a first part of a second hybrid fin. The method further includes filling the first trench with a dielectric material disposed over the first hybrid fin and over the first part of the second hybrid fin. Thereafter, a second portion of the dummy gate is removed to form a second trench and the second trench is filled with a metal layer. The method further includes etching-back the metal layer, where a first plane defined by a first top surface of the metal layer is disposed beneath a second plane defined by a second top surface of a second part of the second hybrid fin after the etching-back the metal layer.
