Abstract:
A method of fabricating a stacked semiconductor device includes forming nanosheet stacks including silicon layers and silicon germanium layers on a substrate. The method includes growing a first epitaxial layer on a source and drain and depositing an interlayer dielectric on the first epitaxial layer. The method includes etching the interlayer dielectric to expose the first epitaxial layer. The method includes etching a portion of the first epitaxial layer and growing a second epitaxial layer on the first epitaxial layer and etching the interlayer dielectric and depositing a first liner in a recess left by the etching, forming a pFET. The method includes etching a portion of the first liner and removing the second epitaxial layer leaving a portion of the first epitaxial layer exposed and depositing a second insulator layer on the first epitaxial layer, forming an nFET. The pFET and nFET are disposed adjacent to one another vertically.

Claim (Index 10):
A method of operating a nanosheet semiconductor device, the method comprising:\n transporting a current laterally through the nanosheet semiconductor device; wherein a pFET and an nFET of the nanosheet semiconductor device are disposed vertically adjacent to one another, and a drain of the pFET and a drain of the nFET are electrically connected; and wherein the nanosheet semiconductor device comprises at least two stacked epitaxial layers, wherein the stacked epitaxial layers comprise different materials, and wherein the stacked epitaxial layers define the drain of the pFET and the drain of the nFET.
