Abstract:
A semiconductor device manufacturing method comprising:a step in which a wafer having electrode pads formed at primary surfaces of semiconductor elements and means for electrical connection provided at said electrode pads is prepared; a step in which protective tape is bonded onto rear surfaces of said semiconductor elements, wherein the rear surfaces are opposite to the primary surfaces of the semiconductor elements; a step in which said wafer is set at a die and said primary surfaces of said semiconductor elements are sealed with a resin layer; a step in which a front surface of said resin layer is polished; a step in which external connection terminals are mounted to said means for electrical connection exposed at said front surface of said resin layer; and a step in which said wafer having undergone the preceding steps is divided into individual pieces, wherein said semiconductor elements are sealed with said resin layer after said protective tape is bonded onto the rear surfaces of said semiconductor elements.
