Method for fabricating electronic device

摘要

After a hole is formed in a low dielectric constant film on a substrate, a protective film is formed on the wall surface of the hole or an electron acceptor is caused to be adsorbed by or implanted in the low dielectric constant film exposed at the wall surface of the hole. Otherwise, resist residue is left on the wall surface of the hole. Then, a resist pattern having an opening corresponding to a wire formation region including a region formed with the hole is formed by using a chemically amplified resist.
