ABSTRACT:
A method of manufacturing semiconductor devices comprises steps of selectively forming metal leads on the surface a semiconductor substrate, and immersing the semiconductor substrate in a solution containing dissolved metal for depositing the dissolved metal on the surfaces of the metal leads. The solution contains dissolved metal having an ionization tendency equal to or smaller than ionization of the metal leads.
