Patent ID: 8183104

Claim:
A method of fabricating a nanowire FET (metal oxide semiconductor field effect transistor) device, the method comprising: depositing, in at least two alternating layers, a first semiconductor material and a second semiconductor material to form a semiconductor structure; etching a first layered column and a second layered column in the semiconductor structure; forming a first group of nanowires, where the first group of nanowires comprises the first semiconductor material from the first layered column, and where a channel region in the first group of nanowires consists of the first semiconductor material; forming a second group of nanowires, where the second group of nanowires comprises the second semiconductor material from the second layered column, and where a channel region in the second group of nanowires consists of the second semiconductor material and the second semiconductor material is different than the first semiconductor material; depositing a first gate coupled to the first group of nanowires; and depositing a second gate coupled to the second group of nanowires.
