Abstract:
Devices, structures, and methods thereof for providing a Schottky or Schottky-like contact as a source region and/or a drain region of a power transistor are disclosed. A power transistor structure comprises a substrate of a first dopant polarity, a drift region formed on or within the substrate, a body region formed on or within the drift region, a gate structure formed on or within the substrate, a source region adjacent to the gate structure, a drain region formed adjacent to the gate structure. At least one of the source region and the drain region is formed from a Schottky or Schottky-like contact substantially near a surface of the substrate, comprising a silicide layer and an interfacial dopant segregation layer. The Schottky or Schottky-like contact is formed by low-temperature annealing a dopant segregation implant in the source and/or drain region.

Claim (Index 17):
The power transistor structure of  claim 12 , wherein an electrical coupling between a channel defined by the gate structure and the source region and an electrical coupling between the channel defined by the gate structure and the drain region are optimized by modulating an interfacial dopant segregation layer in the source region and a doping density of a drain extension region.
