摘要
Techniques for forming a smooth silicide without the use of a cap layer are provided. In one aspect, a FET device is provided. The FET device includes a SOI wafer having a SOI layer over a BOX and at least one active area formed in the wafer; a gate stack over a portion of the at least one active area which serves as a channel of the device; source and drain regions of the device adjacent to the gate stack, wherein the source and drain regions of the device include a semiconductor material selected from: silicon and silicon germanium; and silicide contacts to the source and drain regions of the device, wherein an interface is present between the silicide contacts and the semiconductor material, and wherein the interface has an interface roughness of less than about 5 nanometers.
