Abstract: In some implementations, a buffer layer is formed under a source/drain region of a device. A shape of the buffer layer may include a curved top surface having a height that extends to increase coverage of nanosheets of a fin structure of the device. The shape also includes regions having widths that extend towards shallow trench isolation regions of the device. The shape reduces a likelihood of dopants diffusing from the source/drain region into a mesa region of the fin structure. As a result, a performance of the device may be increased by decreasing short channel effects, decreasing an off-current of the device, and decreasing leakage within the device, among other examples.
