Abstract
A method of manufacturing a semiconductor device substrate includes the steps of: arranging on a base a temporary fixing member for temporarily fixing an electronic component; temporarily fixing the electronic component on the base by the temporary fixing member; forming a substrate body on the base and the electronic component; removing a portion of the base which portion corresponds to the electronic component, thereby exposing the temporary fixing member; and removing the temporary fixing member, thereby enabling the electronic component to make an external connection.
Claims4
A semiconductor device substrate, comprising:
- a substrate layer including an insulating layer and an interconnection layer, said insulating layer and said interconnection layer being stacked;
- an electronic component buried in the insulating layer, a bump being formed on said electronic component acting as an electrode of the electronic component;
- and
- a base layer that is disposed in contact with the insulating layer of the substrate layer, said base layer having an opening formed at a portion corresponding to the electronic component to accommodate an externally provided semiconductor element within the base layer, at least an end of the bump being exposed in the opening for connection of the electronic component to the semiconductor element in the opening.
