摘要： Exact alignment of a recrystallized region, which is to be formed in an amorphous or polycrystalline film, is facilitated. An alignment mark is formed, which is usable in a step of forming an electronic device, such as a thin-film transistor, in the recrystallized region. In addition, in a step of obtaining a large-grain-sized crystal-phase semiconductor from a semiconductor film, a mark structure that is usable as an alignment mark in a subsequent step is formed on the semiconductor film in the same exposure step. Thus, the invention includes a light intensity modulation structure that modulates light and forms a light intensity distribution for crystallization, and a mark forming structure that modulates light and forms a light intensity distribution including a pattern with a predetermined shape, and also forms a mark indicative of a predetermined position on a crystallized region.
