Abstract:
1. A method of forming a semiconductor package, the method comprising: placing a plurality of semiconductor chips over a carrier, each of the plurality of semiconductor chips having a first side contact region on a first side and an opposite second side, each of the plurality of semiconductor chips having an active region adjacent the first side, wherein the second side faces the carrier; forming a reconstituted wafer by applying an encapsulant at the plurality of semiconductor chips and the carrier; forming a through opening and a first contact opening in the encapsulant using a common process step; from the first side, forming a first contact via and a second contact via by filling the through opening and the first contact opening with a conductive fill material, wherein upper portions of the first contact via and the second contact via form contact pads for connecting each of the plurality of semiconductor chips to external nodes; separating the reconstituted wafer from the carrier; thinning the first contact via and the reconstituted wafer so as to thin the plurality of semiconductor chips from the second side; and after the thinning, forming a second side conductive plate under a second side contact region from the second side, wherein the second side contact region is coupled to the first contact via through the second side conductive plate; and forming individual packages by singulating the reconstituted wafer, wherein the plurality of semiconductor chips comprise chips configured to regulate current flow in a direction from the first side towards the second side.
