H01L 29/20

Abstract:

A transistor device is provided that comprises a base structure, and a superlattice structure overlying the base structure and comprising a multichannel ridge having sloping sidewalls. The multichannel ridge comprises a plurality of heterostructures that each form a channel of the multichannel ridge, wherein a parameter of at least one of the heterostructures is varied relative to other heterostructures of the plurality of heterostructures. The transistor device further comprises a three-sided gate contact that wraps around and substantially surrounds the top and sides of the multichannel ridge along at least a portion of its depth.

International Classification:

H01L 29/423
H01L 29/20
H01L 29/778
H01L 29/06

Abstract:

A device is provided that comprises a first pillar disposed in a first region and overlying a base structure, and a second pillar disposed in a second region and overlying the base structure and being spaced apart from the first pillar by a device region. A bridge is disposed in the device region with a first end connected to the first pillar and a second end connected to the second pillar. The bridge includes a top, sides, and a bottom. The bridge is formed from one or more heterostructures with an undercut opening extending from the bottom to an underlying structure. A four-sided conductive contact wraps around and substantially surrounds the bridge around its top, its sides, and its bottom along at least a portion of its length between the first and second end.
