Abstract:
Device structures for a field-effect transistor and methods of forming a device structure for a field-effect transistor. A channel region is formed that includes first and second semiconductor layers, and a gate structure is formed that is arranged over the first and second semiconductor layers. First and second source/drain regions are formed in which the second source/drain region is separated from the first source/drain region by the channel region. The first semiconductor layer is composed of a semiconductor material having a first carrier mobility, and the second semiconductor layer is composed of a semiconductor material having a second carrier mobility that is greater than the first carrier mobility of the first semiconductor layer.

Claim (Index 1):
A device structure for a field-effect transistor, the device structure comprising:\n a first source/drain region; a second source/drain region; a channel region arranged laterally between the first source/drain region and the second source/drain region, the channel region including a first semiconductor layer comprised of a first semiconductor material having a first carrier mobility and a second semiconductor layer comprised of a second semiconductor material having a second carrier mobility that is greater than the first carrier mobility of the first semiconductor layer; and a gate structure arranged over the first semiconductor layer and the second semiconductor layer, wherein the first semiconductor layer of the channel region and the second semiconductor layer of the channel region are each arranged in direct contact with a buried oxide layer of a silicon-on-insulator substrate.
