Abstract
A method of manufacturing a substrate having a thin film thereabove includes: forming a thin film above the substrate; and crystallizing at least a predetermined area of the silicon thin film into a crystallized area through relative scan of the silicon thin film which is performed while the thin film is being irradiated with a continuous wave light beam, wherein in the crystallizing, a projection of the light beam on the thin film has a major axis in a direction crossing a direction of the relative scan, and the formed crystallized area includes a strip-shaped first area extending in the direction crossing the direction of the relative scan and a second area adjacent to the strip-shaped first area, the strip-shaped first area including crystal grains having an average grain size larger than that of crystal grains in the second area.
