Abstract

PURPOSE:To eliminate the need for the precious metals such as Au paste, and to reduce cost by forming a conductor, which consists of Al and a metal, which can be soldered, and is shaped selectively through flame spraying technique, to a substrate with an insulating surface layer. CONSTITUTION:Al2O3 powder is sprayed against the surface of an Al plate 31 and the surface is changed into a coarse surface, and the alumina insulating surface layer 32 is deposited through plasma flame spraying. The copper conductors 34 are formed to the soldering section 7 of a copper block 6 for radiation of a power transistor Tr 5, the conductive epoxy resin bonding section 10 of a small Tr 9, etc. through flame spraying. An Al thick wire 11 is connected to the Al conductor 36 from the Tr 5 through ultrasonic bonding, and an Au thin wire 13 is connected to the Al conductor 36 from the Tr 9 through an ultrasonic thermocompression bonding method.
