Abstract: Techniques are disclosed for forming high mobility NMOS fin-based transistors having an indium-rich channel region electrically isolated from the sub-fin by an aluminum-containing layer. The aluminum aluminum-containing layer may be provisioned within an indium-containing layer that includes the indium-rich channel region, or may be provisioned between the indium-containing layer and the sub-fin. The indium concentration of the indium-containing layer may be graded from an indium-poor concentration near the aluminum-containing barrier layer to an indium-rich concentration at the indium-rich channel layer. The indium-rich channel layer is at or otherwise proximate to the top of the fin, according to some example embodiments. The grading can be intentional and/or due to the effect of reorganization of atoms at the interface of indium-rich channel layer and the aluminum-containing barrier layer. Numerous variations and embodiments will be appreciated in light of this disclosure.

Abstract: Semiconductor devices having group III-V material active regions and graded gate dielectrics and methods of fabricating such devices are described. In an example, a semiconductor device includes a group III-V material channel region disposed above a substrate. A gate stack is disposed on the group III-V material channel region. The gate stack includes a graded high-k gate dielectric layer disposed directly between the III-V material channel region and a gate electrode. The graded high-k gate dielectric layer has a lower dielectric constant proximate the III-V material channel region and has a higher dielectric constant proximate the gate electrode. Source/drain regions are disposed on either side of the gate stack.

Abstract: Techniques are disclosed for forming a beaded fin transistor. As will be apparent in light of this disclosure, a transistor including a beaded fin configuration may be formed by starting with a multilayer finned structure, and then selectively etching one or more of the layers to form at least one necked (or relatively narrower) portion, thereby forming a beaded fin structure. The beaded fin transistor configuration has improved gate control over a finned transistor configuration having the same top down area or footprint, because the necked/narrower portions increase gate surface area as compared to a non-necked finned structure, such as finned structures used in finFET devices. Further, because the beaded fin structure remains intact (e.g., as compared to a gate-all-around (GAA) transistor configuration where nanowires are separated from each other), the parasitic capacitance problems caused by GAA transistor configurations are mitigated or eliminated.
