Patent attributes
In one aspect, a method of fabricating an electronic device includes the following steps. An alternating series of device and sacrificial layers are formed in a stack on an SOI wafer. Nanowire bars are etched into the device/sacrificial layers such that each of the device layers in a first portion of the stack and each of the device layers in a second portion of the stack has a source region, a drain region and a plurality of nanowire channels connecting the source region and the drain region. The sacrificial layers are removed from between the nanowire bars. A conformal gate dielectric layer is selectively formed surrounding the nanowire channels in the first portion of the stack which serve as a channel region of a nanomesh FET transistor. Gates are formed surrounding the nanowire channels in the first and second portions of the stack.
