A method of forming crystals comprises applying crystal formation treatment according to vapor depostion to a substrate having a nonnucleation surface with smaller nucleation density and a nucleation surface of amorphous material with larger nucleation density than said nonnucleation surface and an area sufficiently small such that crystal growth may occur from only a single nucleus, the step of nucleation to form a single nucleus selectively on said nucleation surface and the step of crystal growth to permit a crystal to grow from said single nucleus being conducted under different crystal forming conditions.
