摘要: A method comprises forming a barrier layer for copper metallization, selectively silicon film on surface of wiring formed the main semiconductor substrate, and reacting with non-copper metal and/or nitrogen to form in self-aligned manner relative wiring. In method, capacitance increase wirings is prevented, has satisfactory property protecting wirings.
