Abstract:
A method for fabricating a nanosheet semiconductor structure includes forming a first nanosheet field effect transistor (FET) structure having a first inner spacer comprised of a first material and a second nanosheet FET structure having second inner spacer comprised of a second material. The first material is different than the second material. The first nanosheet FET structure is formed by creating a first inner spacer formation within a first silicon germanium (SiGe) channel, wherein the first SiGe channel is comprised in a first channel region of a first FET region. The second nanosheet FET structure is formed by creating a second inner spacer formation within a second SiGe channel, wherein the second SiGe channel is comprised in a second channel region of a second FET region.

Claim (Index 5):
The method of  claim 1 , further comprising:\n forming a first stack on the first FET region and a second stack on the second FET region, wherein the first stack comprises a first substrate, the one or more first Si nanosheets, and the one or more first SiGe nanosheets, and wherein the second stack comprises the second substrate, the one or more second Si nanosheets, and the one or more second SiGe nanosheets; forming a first pad insulator on the first channel region and a second pad insulator on the second channel region; forming a first gate on the first pad insulator and a second gate on the second pad insulator; forming a first hard mask on the first gate and a second hard mask on the second gate; forming a first spacer on the first channel region, the first gate, and the first hard mask, and a second spacer on the second channel region, the second gate, and the second hard mask, wherein each spacer comprises silicon mononitride (SiN); and forming the first channel region from the first stack and the second channel region from the second stack.
