摘要： At least one semiconductor fin is formed over an insulator layer. Portions of the insulator layer are etched from underneath the at least one semiconductor fin. The amount of the etched portions of the insulator is selected such that a metallic gate electrode layer fills the entire gap between the recessed surfaces of the insulator layer and the bottom surface(s) of the at least one semiconductor fin. An interface between the metallic gate electrode layer and a semiconductor gate electrode layer contiguously extends over the at least one semiconductor fin and does not underlie any of the at least one semiconductor fin. During patterning of a gate electrode, removal of the semiconductor material in the semiconductor gate electrode layer can be facilitated because the semiconductor gate electrode layer is not present under the at least one semiconductor fin.

摘要： 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.

摘要： An alternating stack of two different semiconductor materials is patterned to include two pad regions and nanowire regions. A semiconductor material is laterally etched selective to another semiconductor material to form a nanomesh including suspended semiconductor nanowires. Gate dielectrics, a gate electrode, and a gate cap dielectric are formed over the nanomesh. A dielectric spacer is formed around the gate electrode. The semiconductor materials in the two pad regions and physically exposed portions of the nanomesh are removed employing the dielectric spacer and the gate cap dielectric as an etch mask. A source region and a drain region are epitaxially grown from end surfaces of the nanomesh.
