ABSTRACT:
A method for producing a semiconductor device according to the present invention includes the steps of: disposing a functional element in each cavity of a multi-cavity circuit board, the multi-cavity circuit board having a number of cavities opening upward; overlaying a sealing resin sheet with a predetermined thickness containing, as a sealing resin, one of a thermoplastic resin and a thermosetting resin which is melted by heating and is cured by further heating on the multi-cavity circuit board so as to cover all of the cavities thereof; heating and pressurizing the sealing resin sheet on the multi-cavity circuit board so that the sealing resin sheet is melted to be filled in each of the cavities; and curing the molten resin filled in each of the cavities.
