ABSTRACT:
A conductor substrate for mounting a semiconductor element, at least a portion thereof mounting the semiconductor element being sealed with an insulating resin, wherein an uppermost surface layer of the conductor substrate comprises copper or an alloy thereof, and the conductor substrate is partly or entirely covered with a layer of copper oxide containing a hydroxide formed upon the surface treatment of the conductor substrate and a process of producing the conductor substrate as well as a process for the production of a semiconductor device using the conductor substrate.
