Abstract
A blank and a semiconductor device include a composite panel with semiconductor chips embedded in a plastic package molding compound. The blank includes a composite panel with semiconductor chips arranged in rows and columns in a plastic package molding compound with active upper sides of the semiconductor chips forming a coplanar surface area with the upper side of the composite panel. The blank further includes an orientation indicator impressed into the plastic package molding compound when the semiconductor chips are embedded within the molding compound.
Claims15
A method for producing semiconductor devices, the method comprising:
- producing a semiconductor wafer with a plurality of semiconductor chip positions;
- separating the semiconductor wafer into a plurality of individual semiconductor chips, each semiconductor chip including an active upper side, edge sides and a rear side;
- loading a carrier with the semiconductor chips in semiconductor device positions arranged in rows and columns such that the active upper sides of the semiconductor chips are fixed to the carrier;
- applying a plastic package molding compound via a molding process to the carrier such that an orientation indicator is impressed into the plastic package molding compound and the semiconductor chips including the rear and edge sides of the semiconductor chips are embedded into the plastic package molding compound;
- removing the carrier from the plastic package molding compound to form a self-supporting blank comprising a composite panel, wherein the composite panel includes the orientation indicator, semiconductor chips embedded within the composite panel, and an upper side of the composite panel is substantially coplanar with exposed active upper sides of the semiconductor chips;
- using the orientation indicator to determine an orientation of the self-supporting blank for applying a wiring structure to the upper side of the composite panel and the active upper sides of the semiconductor chips;
- and
- separating the blank into individual semiconductor devices.
A method comprising:
- producing a semiconductor wafer with a plurality of semiconductor chip positions;
- separating the semiconductor wafer into a plurality of individual semiconductor chips, each semiconductor chip including at least one active upper side;
- loading a carrier with the semiconductor chips in the plurality of semiconductor device positions by fixing the at least one active upper side of the plurality of semiconductor chips to the carrier;
- applying a plastic package molding compound to the carrier to impress an orientation indicator into the plastic package molding compound and to embed at least one edge side of the plurality of semiconductor chips into the plastic package molding compound;
- removing the carrier from the plastic package molding compound to form a self-supporting blank comprising a composite panel comprising the orientation indicator and the plurality of embedded semiconductor chips;
- using the orientation indicator to determine an orientation of the self-supporting blank for applying a wiring structure to an upper side of the composite panel and the at least one active upper side of the plurality of semiconductor chips;
- and
- separating the blank into individual semiconductor devices.
