    摘要: A method of forming a semiconductor device is provided that includes forming a gate structure on a channel portion of a semiconductor substrate, forming an interlevel dielectric layer over the gate structure, and forming a opening through the interlevel dielectric layer to an exposed surface of the semiconductor substrate containing at least one of the source region and the drain region. A metal semiconductor alloy contact is formed on the exposed surface of the semiconductor substrate. At least one dielectric sidewall spacer is formed on sidewalls of the opening. An interconnect is formed within the opening in direct contact with the metal semiconductor alloy contact.
