Patent ID: 8859316

Claim:
A method of manufacturing a Schottky junction field-effect sensor, comprising: thinning a semiconductor layer of a semiconductor substrate with an embedded dielectric layer; forming a channel region, a first electrode region, and a second electrode region within the semiconductor layer and abutting the embedded dielectric layer; depositing a silicon nitride layer on the entire width of the channel region; patterning the silicon nitride layer; converting the first electrode region and the second electrode region into a metal silicide, thereby forming a first electrode and a second electrode; implanting an impurity by blanket implantation, wherein the impurity is selected from the group consisting of boron, arsenic, indium, phosphorous, and aluminum; diffusing the impurity to an interface between the channel region and the metal silicide by Thermal Rapid Annealing to form an interface layer comprising the impurity in an amount of about 1·10 18 atoms cm −3 to about 1·10 23 atoms cm −3 within the channel region between the metal silicide and the channel region covered by the silicon nitride; removing the silicon nitride layer; and providing a surface treatment of the channel region.
