Patent ID: 7642132

Claim:
A method of making a three-dimensional package, comprising: (a) providing a semiconductor body, having a first surface and a second surface, the first surface having at least one pad and a protection layer exposing the pad; (b) forming at least one blind hole on the first surface of the semiconductor body; (c) forming an isolation layer on the side wall of the blind hole; (d) forming a conductive layer covering the pad, the protection layer and the isolation layer; (e) patterning the conductive layer; (f) removing a part of the second surface of the semiconductor body and a part of the isolation layer, so as to expose a part of the conductive layer; (g) forming a solder on the lower end of the conductive layer; (h) stacking a plurality of the semiconductor bodies, and performing a reflow process; and (i) cutting the stacked semiconductor bodies, so as to form a plurality of three-dimensional packages.
