Abstract:
1. A method for producing semiconductor devices with a carrier sheet with adhesive film, wherein each of the semiconductor devices includes a plastic package with a semiconductor chip, the method comprising: producing a semiconductor wafer including a plurality of semiconductor chips that are arranged in rows and columns and include active upper sides and back sides, wherein the active upper sides are provided with contact areas; separating the semiconductor wafer into individual semiconductor chips; producing a carrier sheet including a double-sided adhesive film applied to an upper side of the carrier sheet, wherein the adhesive film includes a thermoactive film underside and a film upper side, the film underside is adhesively fixed on the upper side of the carrier sheet, and the film upper side remains freely accessible and includes semiconductor device positions arranged in rows and columns; loading the freely accessible film upper side with the individual semiconductor chips, wherein the individual semiconductor chips are arranged with the active upper sides of the semiconductor chips on the film upper side of the adhesive film in the semiconductor device positions; forming deactivated portions of the film upper side that are not covered with semiconductor chips so as to reduce the adhesive effect of the deactivated portions; applying a plastic package molding compound film upper side so as to embed the semiconductor chips in the plastic package molding compound and to form a panel with a coplanar surface that includes the plastic package molding compound and active upper sides of the semiconductor chips; removing the carrier sheet from the thermoactive film underside of the double-sided adhesive film, and subsequently removing the double-sided adhesive film from the coplanar surface; forming a panel by applying to the coplanar surface a wiring structure with external contact areas and with interconnects from contact areas of the semiconductor chips to the external contact areas; and separating the panel into individual semiconductor devices.
