Abstract:
A method of manufacturing a device includes forming a plurality of stacks of alternating layers on a substrate, constructing a plurality of nanosheets from the plurality of stacks of alternating layers, and forming a plurality of gate dielectrics over the plurality of nanosheets, respectively. The method allows for the modulation of nanosheet width, thickness, spacing, and stack number and can be employed on single substrates. This design flexibility provides for design optimization over a wide tuning range of circuit performance and power usage.
