Abstract
A method for manufacturing a semiconductor device is provided. A resin paste is applied to a wiring base including a wiring pattern. Then, a semiconductor chip having a plurality of electrodes is mounted to the wiring base. The electrodes and the wiring pattern face one another and are electrically connected. The wiring base and the semiconductor chip are bonded by curing the resin paste. The wiring pattern includes a wiring that continuously includes two or more first parts located inside a semiconductor chip mounting region and a second part that connects at least two of the first parts. The second part is located outside the semiconductor chip mounting region.
