Abstract: Embodiments of present invention provide a transistor structure. The transistor structure includes a composite channel of multiple channel layers of different materials, wherein the multiple channel layers are separated from each other by an isolation layer and a material of the isolation layer has a bandgap that is wider than bandgaps of the different materials of the multiple channel layers; a charge trapping layer surrounding the composite channel; a gate metal surrounding the charge trapping layer; and source/drain regions at a first and a second end of the composite channel. A method of forming the same is also provided.

Abstract: Provided is a stacked field-effect transistor (FET). The stacked FET comprises a top active region. The width of the top of the top active region is smaller than the width of bottom of the top active region. The stacked FET further comprises a top contact in direct contact with a top surface of the top active region. The stacked FET further comprises a bottom active region located substantially below the top active region. The stacked FET further comprises a bottom contact in direct contact with a top surface of the bottom active region. The bottom contact is wider at a top end than at a bottom end.

Abstract: A gate-all-around device includes a plurality of channel layers vertically stacked over a substrate, an inner spacer located between each of the plurality of channel layers, source/drain regions in contact with opposite ends of a first portion of the plurality of channel layers, and a first dielectric layer on opposite ends of a second portion of the plurality of channel layers located in a spacer region that is adjacent to the source/drain regions. A width of the first dielectric layer and the second portion of the plurality of channel layers is equal to a width of the inner spacer located between each of the plurality of channel layers.

Abstract: Embodiments described herein provide for integrated input/output and logic devices for nanosheet technology and methods of fabrication for the devices. The types of transistors used for input/output devices and logic devices may differ such that, for example, input/output devices may use EG (Extended Gate) Field Effect Transistors (FET) while logic devices may use Suspended Gate (SG) FETs. Co-locating SG and EG devices on a single die provides for a fabricator to assure alignment between the nanosheets used in the SG and EG devices (improving consistency in the device characteristics on a single die) and reduce overall space requirements for the hardware used by input/output and logic devices.
