Method for manufacturing semiconductor device, adhesive sheet for use therein and semiconductor device

摘要

A method for manufacturing a semiconductor device includes the steps of: (1) forming a plurality of electrically conductive parts on portions of an adhesive layer of an adhesive sheet, the adhesive sheet having a base layer and the adhesive layer; (2) attaching at least one semiconductor element having electrodes to the adhesive layer, wherein an electrode-free side of the semiconductor element is attached to the adhesive layer; (3) electrically connecting a wire between each of the electrically conductive parts and each of the electrodes of the semiconductor element; (4) sealing the semiconductor element in a sealing resin to form a semiconductor device on the adhesive sheet; and (5) separating the adhesive sheet from the semiconductor device. This method enables the production of thin semiconductor devices with a surface mount type.
