FORMATION METHOD AND STRUCTURE FOR A WELL-CONTROLLED METALLIC SOURCE/DRAIN SEMICONDUCTOR DEVICE

摘要

A device and method for forming a semiconductor device include growing a raised semiconductor region on a channel layer adjacent to a gate structure. A space is formed between the raised semiconductor region and the gate structure. A metal layer is deposited on at least the raised semiconductor region. The raised semiconductor region is silicided to form a silicide into the channel layer which extends deeper into the channel layer at a position corresponding to the space.
