Abstract:
Embodiments of the present invention provide methods for fabricating a semiconductor device with selective oxidation. One method may include providing a semiconductor substrate including a stack of two semiconductor layers; depositing an insulating material on the semiconductor substrate; forming a set of fins; selectively oxidizing one of the semiconductor layers; forming a dummy gate structure and a set of spacers along the sides of the dummy gate structure; forming a source drain region adjacent to the dummy gate structure; removing the dummy gate structure; and releasing the selectively oxidized semiconductor layer.

Claim (Index 1):
A method for fabricating a semiconductor device with selective oxidation, the method comprising:\n depositing a stack of two crystalline semiconductor layers over a base layer, wherein the base layer comprises a semiconductor substrate and a first insulator layer; forming a selectively oxidized crystalline semiconductor layer by selectively oxidizing a first of the two crystalline semiconductor layers to yield a selectively oxidized layer that serves as an insulator for a second of the two crystalline semiconductor layers, wherein the stack of two crystalline semiconductor layers maintain a layered configuration after oxidation of the first of the two crystalline semiconductor layers; forming a dummy gate and a set of sidewall spacers positioned adjacent to the dummy gate structure, in direct contact with sidewalls of the dummy gate; forming source and drain regions in contact with each side of the selectively oxidized layer and the second of the two crystalline semiconductor layers etching the selectively oxidized crystalline semiconductor layer; removing the dummy gate; and forming a replacement gate layer between a plurality of walls within the set of sidewall spacers.
