Abstract

A wiring circuit layerhaving a connecting conductor partthat can be connected to an electrodeof a semiconductor elementis formed on a metal support substratein a way such that the wiring circuit layer can be separated from the substrate, and that the connecting conductor partis exposed on the upper face of the wiring circuit layer. The wiring circuit layeris laminated on the elementwhile in a wafer state, and the connecting conductor partand the electrodeare connected. Subsequently, the support substrateis peeled from the wiring circuit layer, and the wafer is diced, whereby individual semiconductor devices are obtained.
