Abstract:
The current disclosure describes semiconductor devices, e.g., transistors including a thin semimetal layer as a channel region over a substrate, which includes bandgap opening and exhibits semiconductor properties. Described semiconductor devices include source/drain regions that include a thicker semimetal layer over the thin semimetal layer serving as the channel region, this thicker semimetal layer exhibiting metal properties. The semimetal used for the source/drain regions include a same or similar semimetal material as the semimetal of the channel region.

Claim (Index 14):
A method, comprising:\n forming a first semimetal layer of a first thickness on a substrate; forming a dielectric layer of high dielectric constant over the first semimetal layer; forming a dielectric region through patterning the dielectric layer; forming a second semimetal layer of a second thickness over the first semimetal layer and the dielectric region; and forming a first portion and a separated second portion of the second semimetal layer through patterning the second semimetal layer, the first portion of the second semimetal layer being formed over the dielectric region and being separated from the first semimetal layer by the dielectric region; wherein the first semimetal layer and the second semimetal layer include bismuth; the first thickness is within a first range between about 1.5 nm to about 9.5 nm such that the first semimetal layer includes a semiconductor property, and the second thickness is within a second range between about 10 nm to about 100 nm such that the second semimetal layer includes a metal property.
