Abstract

A method for forming a semiconductor structure includes providing a substrate including a plurality of first isolation structures formed therein, wherein the first isolation structures are protruded from a surface of the substrate; conformally forming a semiconductor layer over the substrate and the first isolation structures; forming a sacrificial layer over the semiconductor layer to form a planar surface over the substrate; and removing the sacrificial layer, a portion of the semiconductor layer and a portion of each first isolation structure to form at least one first gate structure using a same etchant.
