Patent ID: 8828798

Claim:
A method of forming a semiconductor die assembly, comprising: forming a dielectric material over a surface of a base wafer; forming a plurality of thermally conductive elements on the dielectric material in electrical isolation from the base wafer; placing conductive through vias of a plurality of laterally spaced semiconductor dice in contact with the thermally conductive elements; disposing at least two semiconductor dice over each semiconductor die of the plurality to form a stack and connecting conductive through vias of the semiconductor dice in a stack with conductive elements extending therebetween; providing a dielectric material between the semiconductor dice in a stack; substantially simultaneously encapsulating at least a periphery of each of the stacks of semiconductor dice on the base wafer with an encapsulant material between and around the stacks of semiconductor dice; and singulating the stacks of semiconductor dice and the base wafer through the encapsulant material and the base wafer between the stacks of semiconductor dice.
