Abstract:
1. A semiconductor embedded module, comprising: a semiconductor device which is provided with or connected with a wiring layer; a first insulating layer (1) which is formed of imide resin or a resin composition containing imide resin and (2) which is provided in the periphery of the wiring layer such that an external connection pad of the wiring layer is exposed; a second insulating layer (1) which is formed of epoxy resin or a resin composition containing epoxy resin, (2) which is directly laminated on a first surface of the first insulating layer opposite to a second surface of the first insulating layer provided on the wiring layer, and (3) which has a grinding rate in a blasting treatment larger than that of the first insulating layer; and a via which is opened onto at least a part of the external connection pad and at least a part of the second insulating layer.
