Claim Text:
1. A method of making a semiconductor device, comprising: providing a substrate formed from a semiconductor material and including a plurality of first conductive vias formed through the substrate; forming an insulating layer over the substrate and first conductive vias; removing a portion of the insulating layer to expose the first conductive vias; depositing a conductive material over the substrate in the insulating layer to form conductive traces in contact with the first conductive vias; providing a plurality of first semiconductor die including second conductive vias formed through the first semiconductor die; disposing the plurality of first semiconductor die over the substrate including an active surface oriented toward the substrate; forming an interconnect structure on the conductive traces and a surface of the substrate outside the first semiconductor die and between side-by-side ones of the first semiconductor die; disposing a second semiconductor die over the first semiconductor die and coupled to the interconnect structure with each of the first semiconductor die completely within a footprint of the second semiconductor die, the second semiconductor die being electrically connected through the interconnect structure to the conductive traces of the substrate and through the second conductive vias to the first semiconductor die; disposing a thermal interface material on the second semiconductor die; and disposing a heat spreader over the second semiconductor die and extending to a top surface of the conductive traces of the substrate after disposing the thermal interface material on the second semiconductor die.
