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. |

1. A method for fabricating a semiconductor structure, the method comprising:
providing a semiconductor substrate comprising a plurality of fin structures formed thereon; depositing a conformal liner over the fin structures; removing a first portion of the conformal liner, leaving a first space between the fins structures; forming a first metal gate in the first space between the fin structures; removing a second portion of the conformal liner, leaving a second space between the fin structures; and forming a second metal gate in the second space between the fin structures. |
