Abstract:
A production process for a semiconductor device having a metal electrode provided on a semiconductor substrate thereof, the semiconductor device production process comprising the steps of:forming a metal electrode portion on a surface of another substrate for electrode transfer by depositing a material for the metal electrode, by plating, onto a seed film that is provided on the surface of the electrode transfer substrate; and transferring the metal electrode portion from the electrode transfer substrate onto the semiconductor substrate by pressing together the electrode transfer substrate and the semiconductor substrate, leaving the seed film on the surface of the electrode transfer substrate wherein the electrode transfer substrate has a patterning film provided on a surface thereof and partly covering a surface of the seed film to expose a portion of the seed film on which the metal electrode portion is to be formed, wherein the seed film is composed of such a material that the metal electrode portion has a lower adhesion affinity for the seed film than for a portion of the semiconductor substrate onto which the metal electrode portion is to be transferred.
