Abstract:
1. A metal semiconductor alloy contact on a semiconductor layer, the metal semiconductor alloy contact comprising: a textured metal semiconductor alloy layer having a thickness of less than 25 Å extending to a first depth of the semiconductor layer; and a templated metal semiconductor alloy layer in direct contact with the textured metal semiconductor alloy layer and extending to a second depth of the semiconductor layer greater than the first depth, the templated metal semiconductor alloy layer having the same crystalline orientation as the textured metal semiconductor alloy, and comprising metal semiconductor crystal grains having an in-plane texture to semiconductor crystal grains of the semiconductor at an interface between the semiconductor layer and the templated metal semiconductor alloy, wherein the templated metal semiconductor alloy has a grain size that is greater than 2× a thickness of the metal semiconductor alloy contact.
