ABSTRACT:
On a semiconductor substrate, chips to be products and alignment chips located at a portion a part thereof is left out from a peripheral part of the semiconductor substrate are formed. Contact holes and alignment marks are formed at the chips to be products and the alignment chips. Covering the alignment chips with alignment mark cover parts of a substrate holder, a material for metal wiring is deposited on the semiconductor substrate to form a metal film on the substrate. A mask pattern is formed on the metal film using the alignment marks of the alignment chips on which the metal film is not formed.
