LAYERED BODY WITH SUPPORT SUBSTRATE, METHOD FOR FABRICATING SAME, AND METHOD FOR FABRICATING MULTI-LAYER WIRING SUBSTRATE

摘要

A layered body with a support substrate, the layered body being on the support substrate and comprising: metal foil B which is arranged on the support substrate and on which a wiring pattern is not formed; an insulating layer B which is arranged on the metal foil B; metal foil C which is arranged on the insulating layer B and on which a wiring pattern is not formed; non-through holes for a product and non-through holes for an alignment mark that penetrate the metal foil C and the insulating layer B and reach the metal foil B; and the alignment mark of a dot pattern in which the non-through holes for the alignment mark are filled by plating and gathered and arranged in an individually independent state.
