Abstract
A method of manufacturing a semiconductor device comprises a semiconductor body (1) having a surface (2), which is adjoined by regions of silicon (3, 4, 5 and 6) and regions of insulating material (8 and 9), the regions of silicon being provided with a top layer (10) of a metal silicide by depositing metal on the surface while heating the semiconductor body to a temperature at which metal silicide is formed during the deposition. According to the invention, cobalt or nickel is deposited while the semiconductor body is heated to a temperature at which cobalt or nickel silicide is formed. Thus, metal silicide does not grow over parts of the regions of insulating material adjoining directly the regions of silicon.
