Abstract: PURPOSE:To manufacture an element having a characteristic according to a design by a method wherein an amount of an etching operation, using HCl gas, which is executed before an epitaxial growth operation is controlled in order to execute an accurate alignment operation. CONSTITUTION:After the surface of a 100 silicon wafer substrate 1 having a first cavity part 4 for alignment use has been etched by using HCl gas, an epitaxial growth operation by a CVD method is executed by using a raw gas; an epitaxial layer 5 having a second cavity part 6 corresponding to the first cavity part 4 is formed. During this process, an amount of an etching operation by the HCl gas is set at 5000Angstrom  or lower.
