Abstract:
A semiconductor device manufacturing method, comprising:arranging a dam made of a highly heat-shrinkable material on a circuit substrate, the circuit substrate having at least one surface provided with a semiconductor element, a conductive pattern, and a conductor having one end connected to the semiconductor element and another end connected to the conductive pattern, wherein the dam defines a region including the semiconductor element, the conductor, and a part of the conductive pattern connected to the another end of the conductor; injecting a sealer into the region defined by the dam and using the sealer to seal the semiconductor element, the conductor, and the part of the conductive pattern connected to the another end of the conductor, the sealer having a heat shrinkability that is lower than a heat shrinkability of the dam; and cooling the dam to remove the dam.
