Abstract

Three-dimensional structures having a suitable geometrical configuration are directly formed on one major surface of a substrate so that an epitaxial molecular beam may be incident on preselected regions, and the angles of incidence of epitaxial molecular beams are varied. As a result the arrival rates of molecular beams are varied from one region to another on the substrate so that a three-dimensional epitaxial layer in which the physical properties are different from one region of a submicron across to another may be grown.
