Abstract

The thickness of a thin film of an element semiconductor may be determined by counting the number of cycles of gaseous component introductions within a crystal growth vessel. Each cycle permits at most one monolayer of growth since the pressure in the vessel during gaseous component introduction is maintained under a saturation condition. The temperature to which a substrate in the vessel is heated is that for which epitaxial growth results.
