Abstract: A projection system includes a projection device that projects drawings individually onto a plurality of work spots in a work site. The projection device includes a driver that changes an orientation of the projection device. When drawings are individually projected onto a first work spot and a second work spot in a stated sequence, and the second work spot is outside a projection angle that is projectable by the projection device, the driver changes the orientation of the projection device to include the second work spot within the projection angle after work at the first work spot is finished. The first work spot and the second work spot are included in the plurality of work spots.

In the trench forming step, a trench is formed on a first main surface of a semiconductor substrate having a device structure formed thereon. In the laser irradiation step, a laser is irradiated from a second main surface of the semiconductor substrate to a plane surface that is positioned and extends at a predetermined depth of the semiconductor substrate. In the peeling step, a device layer is peeled off from the semiconductor substrate along the plane surface on which the laser is irradiated. The peeling step may be performed in a state in which the trenches are either unfilled or filled with a material having a lower coefficient of thermal expansion than the semiconductor substrate.
