Abstract
Provided are a semiconductor device and a method of forming the same. The semiconductor device includes a substrate, a plurality of semiconductor nanosheets, a source/drain (S/D) region, a gate stack, and a liner layer. The substrate includes at least one fin. The plurality of semiconductor nanosheets are stacked on the at least one fin. The S/D region abuts the plurality of semiconductor nanosheets. The gate stack wraps the plurality of semiconductor nanosheets. The liner layer lines a bottom surface and a sidewall of the S/D region and is sandwiched between the S/D region and the gate stack.
