Abstract:
1. A module with a built-in semiconductor comprising an electrically insulating core layer containing an inorganic filler and a thermosetting resin, a first wiring layer formed on one surface of the core layer and a second wiring layer formed on the other surface of the core layer, inner vias which are formed in the core layer and connect the wiring layers electrically, and a semiconductor device incorporated in the core layer, wherein at least the first wiring layer forms a circuit board together with one or more electrically insulating layers and/or one or more wiring layers, the semiconductor device is connected to the first wiring layer by a flip-chip bonding, and a space is formed between a functional element-formed surface of the semiconductor device and a surface of the circuit board on which surface the first wiring layer is disposed except for regions where the semiconductor device and the first wiring layer are connected.
