Abstract:
A method of forming a contact to a semiconductor device that includes forming a vertically orientated channel region on semiconductor material layer of a substrate; and forming a first source/drain region in the semiconductor material layer. The method may continue with forming a metal semiconductor alloy contact on the first source/drain region extending along a horizontally orientated upper surface of the first source/drain region that is substantially perpendicular to the vertically orientated channel region, wherein the metal semiconductor alloy contact extends substantially to an interface with the vertically orientated channel region. Thereafter, a gate structure is formed on the vertically orientated channel region, and a second source/drain region is formed on the vertically orientated channel region.

Claim (Index 1):
A vertical transistor comprising:\n a vertically orientated channel region on semiconductor material layer of a substrate; a first source/drain region in the semiconductor material layer; a metal semiconductor alloy contact on the first source/drain region extending along a horizontally orientated upper surface of the first source/drain region, wherein the metal semiconductor alloy contact extends substantially to an interface with the vertically orientated channel region, wherein an edge of the metal semiconductor alloy contact is aligned with a sidewall of the vertically orientated channel region; a gate structure on the vertically orientated channel region; and a second source/drain region on the vertically orientated channel region.
