Abstract:
The present disclosure provides a semiconductor structure, including an active region with a first surface; an isolated region having a second surface, surrounding the active region, the first surface being higher than the second surface; and a metal gate having a plurality of metal layers disposed over the first surface and the second surface. A ratio of a thinnest portion and a thickest portion of at least one of the plurality of metal layers is greater than about 40%.

Claim (Index 8):
A field effect transistor (FET), comprising:\n an active region surrounded by an isolated region, a sidewall and a first surface of the active region protruding from a second surface of the isolated region; and a metal gate at least covering the sidewall and the first surface of the active region, wherein an Al-containing layer of the metal gate comprises:\n a first thickness in proximity to the first surface of the active region; and \n a second thickness in proximity to a corner connecting the first surface and the sidewall of the active region, and \n a thickness ratio of the second thickness and the first thickness is greater than about 40%.
