Abstract:
1. A manufacturing method for semiconductor devices, comprising the steps of: (a) preparing a first base material having a chip mounting area and a plurality of electrode areas arranged around the chip mounting area; (b) mounting a semiconductor chip having a first main surface, a sensor area formed on the first main surface, a plurality of pads formed on the first main surface and electrically coupled with the sensor area, a first back surface opposed to the first main surface, and first side surfaces positioned between the first main surface and the first back surface over the chip mounting area through a first adhesive such that the first back surface is opposed to the chip mounting area; (c) mounting a second base material having a second main surface, a second back surface opposed to the second main surface, second side surfaces positioned between the second main surface and the second back surface, and an opening extended from the second main surface to the second back surface, the opening being covered with a protective sheet stuck over the second main surface, over the first main surface of the semiconductor chip through a second adhesive such that the second back surface is opposed to the first main surface of the semiconductor chip; (d) respectively electrically coupling the pads of the semiconductor chip and the electrode areas through a plurality of conductive members; and (e) sealing the semiconductor chip, the second base material, and the conductive members with a resin such that part of the second side surfaces of the second base material and the second main surface of the second base material are exposed, and forming a sealing body, wherein the sealing body is formed by the steps of: (e1) preparing a molding die having an upper die and a lower die opposed to the upper die; (e2) arranging a film between the upper die and the lower die; (e3) arranging the first base material on which the semiconductor chip and the second base material are mounted between the film and the lower die; (e4) after the step (e3), clamping the upper die and the lower die, and biting a part of the second base material into the film; (e5) after the step (e4), supplying the resin between the film and the lower die, and forming the sealing body; and (e6) after the step (e5), opening the upper die and the lower die, and taking the first base material with the sealing body formed thereon out of the molding die.
