Abstract:
An asymmetric field-effect transistor having different gate-to-source and gate-to-drain overlaps allows lower parasitic capacitance on the drain side of the device and lower resistance on the source side. Source and drain regions having different configurations can be formed simultaneously using the same precursor materials.

Claim (Index 1):
A method of fabricating an asymmetric field-effect transistor device, comprising:\n obtaining a structure including a semiconductor substrate having a first portion including a recess extending vertically therein, a second portion lacking a recess, and a channel region between the first and second portions, the recess being formed between a pair of dummy gates and including undercut portions extending beneath the dummy gates; epitaxially growing an embedded source region within the recess in the first portion of the semiconductor substrate; epitaxially growing a cladded drain region on the second portion of the semiconductor substrate, wherein the embedded source region and the cladded drain region are grown simultaneously; depositing a gate dielectric layer over the channel region of the semiconductor substrate, and forming a metal gate on the gate dielectric layer, wherein forming the metal gate includes replacing at least one of the dummy gates with the metal gate.
