In a process for producing the component-embedded substrate, a first electronic component is connected and fixed onto a first electrode pattern with a conductive bonding material, the first electrode pattern being provided on a first supporting layer. A second supporting layer including a second electrode pattern is press-bonded onto the electronic component-fixed surface of the first supporting layer with a first prepreg therebetween to perform transfer. Then, the first supporting layer and the second supporting layer are separated from the first prepreg. After separation, the first prepreg is cured. A second electronic component is connected and fixed onto the back surface of the second electrode pattern with a conductive bonding material. A third supporting layer including a third electrode pattern is press-bonded onto the second electronic component-fixed surface with a second prepreg therebetween to perform transfer. Then, the third supporting layer is separated from the second prepreg, and the second prepreg is cured. In this manner, the prepregs and electrode patterns are sequentially laminated, thereby reducing the connection resistance between laminated electrode patterns or between an electrode pattern and an electronic component.

A semiconductor device is made by forming contact pads on a sacrificial carrier. The contact pads may be formed on a pillar. A semiconductor die is mounted to electrically connect to the contact pads with solder bumps or wire bonds. The semiconductor die is encapsulated with molding compound. The sacrificial carrier is removed. A backside interconnect structure has a first conductive layer formed over the molding compound to electrically connect to the contact pads. A first insulating layer is formed over the first conductive layer. A portion of the first insulating layer is removed to expose the first conductive layer. Solder material is deposited in electrical contact with the first conductive layer. The solder material is reflowed to form a solder bump. A wire bond electrically connects to a contact pad. A front-side interconnect structure can be formed through the molding compound to the contact pads.
