RECONSTITUTION TECHNIQUES FOR SEMICONDUCTOR PACKAGES

摘要

Reconstitution techniques for semiconductor packages are provided. One reconstitution technique is used to encapsulate (348) a plurality of semiconductor packages (336,354,356) into a single multi-chip module (fig. 3e). Solder balls (326) coupled to each package may be partially exposed after reconstitution, which enables the packages to be coupled to another device. Another reconstitution technique is used to couple a plurality of semiconductor packages into a package-on-package module using self-alignment feature(s) (fig. 6k). The self-alignment feature(s) are exposed solder ball(s) (626) that are included in the bottom package of the package-on-package module. The exposed solder ball(s) serve as a frame of reference to other solder balls (624) that are encapsulated by an encapsulation material (634). After the location of these other solders balls are determined, through-mold vias (636a,636b) may be formed in the encapsulation material at locations corresponding to the other solder balls. The top package of the package-on-package module may then be coupled to the bottom package using these solder balls.
