摘要:
A method for forming a Cu thin film on a substrate includes a Cu-CVD step forming a first copper film on predetermined surface of a substrate by a CVD process and a plating step further forming a second copper film on the first copper film by an eletrolytic copper plating process using the first copper film as an electrode. A modifying step modifies the first copper film by exposing it in an active atmosphere between the Cu-CVD step and the plating step. Fine voids can thereby be effectively prevented from being formed in the vicinity of the interface between the first copper film and the second copper film.

In a substrate annealing apparatus, a substrate holder unit including a substrate stage made of carbon with a high emissivity or a material coated with carbon is accommodated in a vacuum chamber to be liftable. Also, a heating unit having a heat radiating surface facing the substrate stage is disposed above the substrate holder unit within the vacuum chamber. The substrate annealing apparatus brings the substrate stage close to the heat radiating surface so that a substrate mounted on the substrate stage can be heated by radiant heat from the heat radiating surface while the heat radiating surface is not in contact with the substrate. The substrate holder unit includes a radiating plate and a reflecting plate made of one of a metal carbide, a metal nitride, and a nickel alloy.
