Abstract:
1. A method of manufacturing a semiconductor device, the method comprising: an attachment step of attaching a supporting substrate to the front surface of a semiconductor wafer using an adhesive, wherein a patterning step of performing patterning, corresponding to a front surface shape of the semiconductor wafer, on a rear surface of the semiconductor wafer; a peeling step of peeling off the supporting substrate from the semiconductor wafer; a dicing step of, after the peeling step, dicing the semiconductor wafer into chips;. a mounting step of mounting the semiconductor on a stage, with the supporting substrate down, after the attachment step; and a positioning step of detecting a mark which is formed on the front surface of the semiconductor wafer and positions the semiconductor wafer from a lower side of the stage and positioning the semiconductor wafer, wherein, in the positioning step, the mark which is formed on the front surface of the semiconductor wafer and positions the semiconductor wafer is detected by a camera, and wherein, in the positioning step, the camera captures an image of the front surface of the semiconductor wafer through an opening which is provided in the stage from the lower side of the stage and the mark for positioning the semiconductor wafer is detected on the basis of the image captured by the camera.
