Abstract
A wiring circuit layerhaving at least a wiring part and an insulating part, whose top and bottom surfaces (A,B) is adhesive surfaces, is formed on a metal support substratein a way such that the layercan be peeled from the substrate. Exposed in the first adhesive surfaceA of the wiring circuit layeris a first connecting conductor part, which is connectable with an electrodeof a first semiconductor elementin a wafer state. After the wiring circuit layeris laminated on and connected to the element, the metal support substrateis peeled from the wiring circuit layerto yield a semiconductor device. Another element may be connected to the other adhesive surfaceB exposed upon the peeling.
