ABSTRACT:
Polycrystalline silicon thin-films having a large grain size are formed by preparing a substrate of amorphous surface comprising first regions containing tin atoms at a higher content and second regions containing tin atoms at a lower content or not substantially containing them, and then heat-treating the substrate to grow crystal grains from crystal nuclei formed only in the first regions.
