Abstract:
1. A method for producing a plurality of semiconductor chips including fragile adhesive film on back sides of the semiconductor chips, the method comprising: producing a semiconductor wafer including a plurality of semiconductor chip positions arranged in rows and columns; applying a back side of the semiconductor wafer to a carrier film; introducing separating joins along the semiconductor chip positions into the upper side of the semiconductor wafer, the separating joins not completely severing the semiconductor wafer; adhesively attaching a semiconductor wafer carrier to an upper side of the, not completely severed, semiconductor wafer; thinning the back side of the semiconductor wafer to the separating joins such that the semiconductor chip positions are separated along the back sides; applying a fragile adhesive film to the back sides of the separated semiconductor chip positions; and singulating the separated semiconductor chip positions, via severing the fragile adhesive film along the separating joins, thereby forming semiconductor chips including respective pieces of fragile adhesive film.
