ABSTRACT:
A method for forming a crystal, which comprises applying, on a substrate having a primary seed comprising a non-single crystaline material having a surface area fine enough to be agglomeratable into a single single-crystalline body by heat treatment and a non-nucleation surface with smaller nucleation density than said primary seed, a heat treatment for agglomerating said primary seed to form a single crystalline seed in an atmosphere containing hydrogen gas at a temperature lower than the temperature at which said primary seed is melted, and applying a crystal growth treatment, thereby permitting a single crystal to grow with said seed as the origination point.
