Abstract:
A method of manufacturing a semiconductor device, comprising:preparing a mold having a upper mold and a lower mold, the lower mold having an area where a the semiconductor wafer having a main surface and a back surface is mounted, the lower mold having an uneven surface in the area, and the upper mold having a resin passage for introducing a melted resin on the semiconductor wafer; placing the semiconductor wafer directly in the area of the lower mold wherein the back surface of the semiconductor wafer contacts the lower mold directly in the area; sandwiching the semiconductor wafer by the upper and lower molds; introducing the melted resin through the resin passage on the main surface of the semiconductor wafer whereby the main surface of the semiconductor wafer is sealed by the resin; and separating the resin sealed semiconductor wafer from the molds.
