Element joining pad for semiconductor device mounting board.

摘要

An element joining pad for a semiconductor device mounting board includes a thick-film metalized layer, a barrier layer, and a Ni plating layer. The thick-film metalized layer is selectively formed on a low-temperature sintered board and consists of one of a metal and an alloy which can be sintered at 500 DEG C or more and 1,200 DEG C or less. The barrier layer is formed on the thick-film metalized layer and constituted by one of a Rh plating layer and a Ru plating layer. The Ni plating layer is formed on the barrier layer.
