Abstract: The method of this invention produces a silicide region on a silicon body that is useful for a variety of purposes, including the reduction of the electrical contact resistance to the silicon body or an integrated electronic device formed thereon. The invented method includes the steps of producing an amorphous region on the silicon body using ion implantation, for example, forming or positioning a metal such as titanium, cobalt or nickel in contact with the amorphous region, and irradiating the metal with intense light from a laser source, for example, to cause metal atoms to diffuse into the amorphous region. The amorphous region thus becomes an alloy region with the desired silicide composition. Upon cooling after irradiation, the alloy region becomes partially crystalline. To convert the alloy region into a more crystalline form, the invented method preferably includes a step of treating the alloy region using rapid thermal annealing, for example.
