Patent ID: 7910442

Claim:
A method for forming a semiconductor device, the method comprising: forming a dielectric layer; partially etching a first portion of a first layer overlying the dielectric layer, wherein: the first layer is a conductive layer; the first portion comprises a top portion and a bottom portion under the top portion; and partially etching comprises removing the top portion of the first portion while the bottom portion of the first portion remains; removing at least a portion of a second layer; after removing the at least a portion of the second layer, completing etching of the first portion of the first layer so that the bottom portion of the conductive layer is removed after removing at least the portion of the second layer; forming a third layer in direct contact with the dielectric layer after completely etching the first portion of the first layer, wherein the third layer is another conductive layer; and completing formation of the semiconductor device, wherein portions of the dielectric layer and the third layer are parts of a transistor.
