Abstract:
1. A semiconductor device comprising: a semiconductor substrate; a channel layer of at least a first III-V semiconductor compound above the semiconductor substrate; a gate stack structure above a first portion of the channel layer; a source region and a drain region above a second portion of the channel layer, the source and the drain (S/D) regions comprising at least a second III-V semiconductor compound; and a first metal contact structure above the S/D regions comprising a first metallic contact layer contacting the S/D regions, the first metallic contact layer comprising at least one metal-III-V semiconductor compound; wherein the S/D regions further comprise a metal-III-V semiconductor compound, and the at least one metal-III-V semiconductor compound in the first metallic contact layer and the metal-III-V semiconductor compound in the S/D regions are nickelide.
