A method for manufacturing a semiconductor device having a substrate on which conductor wiring is disposed, electrodes provided to the conductor wiring, a semiconductor element connected to the electrodes, and a sealing member that covers the semiconductor element, comprises; mounting a plurality of semiconductor elements on the substrate in the X-axial direction and the Y-axial direction, forming marks in the X-axial direction, supplying the sealing material onto the substrate to continuously-covering the plurality of semiconductor elements arranged in the X-axial direction along the marks, dicing the sealing member and the substrate in the Y-axial direction to form cut planes of the sealing member and the substrate in substantially one plane and being a pair of cut planes opposite one another. |
