摘要:
A method for producing a silicide contact. The method comprises the steps of depositing a metal on a SiC substrate; forming an encapsulating layer on deposited metal; and annealing said deposited metal to form a suicide contact. The encapsulating layer prevents agglomeration and formation of stringers during the annealing process.

A transistor is provided that comprises a source region overlying a base structure, a drain region overlying the base structure, and a block of semiconducting material overlying the base structure and being disposed between the source region and the drain region. The block of semiconducting material comprises a gate controlled region adjacent the source region, and a drain access region disposed between the gate controlled region and the drain region. The drain access region is formed of a plurality of semiconducting material ridges spaced apart from one another by non-channel trench openings, wherein at least a portion of the non-channel trench openings being filled with a doped material to provide a depletion region to improve breakdown voltage of the transistor.

One example includes a semiconductor device. The semiconductor device include a carbon nanotube substrate, a self-assembled monolayer, and a gate oxide. The self-assembled monolayer overlies the carbon nanotube substrate and is comprised of molecules each including a tail group, a carbon backbone, and a head group. The gate oxide overlies the self-assembled monolayer, wherein the self-assembled monolayer forms an interface between the carbon nanotube substrate and the gate oxide.

An integrated circuit is disclosed that includes a single channel device having a first portion of a single shared heterostructure overlying a substrate structure in a single channel device area, and a gate contact that is in contact with the first portion of the single shared heterostructure. The integrated circuit also includes a multichannel device comprising a second portion of the single shared heterostructure overlying the substrate structure in a multichannel device area, a barrier layer overlying the second portion of the single shared heterostructure, and a superlattice structure overlying the barrier layer, the superlattice structure comprising a plurality of heterostructures. An isolation region in the single shared heterostructure electrical isolates the single channel device from the multichannel device.

The disclosure relates to a Point Cooler based on a combination of principles, including large area, low current density PN junction cooling, and electron emission from heavily doped shallowly-depleted P tips. Using Junction Cooling rather than thermoelectric cooling enables an all silicon device to be made that favorably competes with the commercial thermoelectric cooling systems. Theoretical values of THOT/TCOLD of 6 or more (in contrast to about 1.5 for other solid state refrigerators) predict this single-stage solid state vacuum electronic cooler can approach 50K at light loading, significantly lower than conventional Bismuth Telluride based thermo electrics. The high Z values for PN junction cooling with wire connection and Tunnel heat extraction opens up solid state vibration-less form fit and function replacement cooling.

A substrate arrangement for high power semiconductor devices includes a SiC wafer having a Si layer deposited on a surface of the SiC wafer. An SOI structure having a first layer of Si, an intermediate layer of SiO2 and a third layer of Si, has its third layer of Si bonded to the Si deposited on the SiC wafer, forming a unitary structure. The first layer of Si and the intermediate layer of SiO2 of the SOI are removed, leaving a pure third layer of Si on which various semiconductor devices may be fabricated. The third layer of Si and deposited Si layer may be removed over a portion of the substrate arrangement such that one or more semiconductor devices may be fabricated on the SiC wafer while other semiconductor devices may be accommodated on the pure third layer of Si.
