CIRCUIT SUBSTRATE AND METHOD FOR MANUFACTURING THE SAME
First Claim
1. A circuit substrate, comprising:
- a core substrate having a cavity penetrating through the core substrate;
a combined component accommodated in the cavity of the core substrate;
a first build-up layer laminated on a first surface of the core substrate and comprising an insulating resin layer such that the insulating resin layer is covering the cavity;
a second build-up layer laminated on a second surface of the core substrate and comprising an insulating resin layer such that the insulating resin layer is covering the cavity; and
a filling resin filling a gap formed between the cavity and the combined component accommodated in the cavity of the core substrate,wherein the combined component comprises an electronic component and a metal block, the electronic component has a terminal surface on a side facing the first surface of the core substrate, and the metal block is superposed to a surface of the electronic component on an opposite side of the electronic component with respect to the terminal surface.
