Abstract

A method for forming a crystal, which comprises applying a crystal forming treatment on a substrate having a free surface on which a deposition surface (S.sub.NDS) with a small nucleation density and a deposition surface (S.sub.NDL) having a sufficiently small area for crystal growth only from a single nucleus and having a greater nucleation density (ND.sub.L) than the nucleation density (ND.sub.S) of said deposition surface (S.sub.NDS) are arranged adjacent to each other, thereby growing a single crystal from said single nucleus.
