Method of eliminating source/drain junction spiking, and device produced thereby

摘要

A method of forming an integrated circuit with a semiconductor substrate is provided. A gate dielectric is formed on the semiconductor substrate, and a gate is formed on the gate dielectric. A metallic layer is formed on the semiconductor substrate, and the metallic layer is reacted with the semiconductor substrate to form an early phase of silicide. Implanted shallow source/drain junctions are formed immediately beneath the silicide. A final phase of the silicide is formed. An interlayer dielectric is deposited above the semiconductor substrate, and contacts are then formed to the silicide.
