ABSTRACT:
A method for forming a crystal comprises applying a crystal forming treatment on a substrate having a free surface comprising a nonnucleation surface (S.sub.NDS) with small nucleation density and a nucleation surface (S.sub.NDL) exposed from said nonnucleation surface having a sufficiently small area for a crystal growing only from a single nucleus and having a greater nucleation density (ND.sub.L) than the nucleation density (ND.sub.S) of said non-nucleation surface (S.sub.NDS), thereby growing a single crystal from said single nucleus.
