发明名称 ASYMMETRIC FINFET SEMICONDUCTOR DEVICES AND METHODS FOR FABRICATING THE SAME
摘要 Asymmetric FinFET devices and methods for fabricating such devices are provided. In one embodiment, a method includes providing a semiconductor substrate comprising a plurality of fin structures formed thereon and depositing a conformal liner over the fin structures. A first portion of the conformal liner is removed, leaving a first space between the fins structures and forming a first metal gate in the first space between the fin structures. A second portion of the conformal liner is removed, leaving a second space between the fin structures and forming a second metal gate in the second space between the fin structures.
