Abstract:
A method of manufacturing a semiconductor device, the method comprising the sequential steps:(a) introducing a wafer containing inlaid copper (Cu) or a Cu alloy into a chamber; (b) treating an exposed surface of the Cu or Cu alloy with a plasma under an RF power while introducing ammonia (NH3) and nitrogen (N2) into the chamber; (c) shutting off the RF power, discontinuing introducing N2, reducing pressure in the chamber to 2 to 4 Torr; and introducing helium (He) into the chamber; (d) ramping up the introduction of trimethylsilane (TMS) into the chamber in a plurality of stages; and (e) depositing a silicon carbide capping layer on the surface of the Cu or Cu alloy in the chamber.
