Abstract:
1. A reproducible vapor phase growth method for growing an epitaxial layer on semiconductor substrates of a single crystal, comprising: measuring a resistivity of arbitrary semiconductor substrates at a room temperature; obtaining respectively a relationship between a heating temperature and a temperature of a surface of the arbitrary semiconductor substrates, for the arbitrary semiconductor substrates having different resistivities, the relationship depending on different cutting positions of the single crystal; setting and adjusting said heating temperature of a semiconductor substrate to be used based on (i) a measured resistivity of the semiconductor substrate to be used and (ii) the obtained relationship between the heating temperature and the temperature of the surface of said semiconductor substrate; and growing the epitaxial layer, wherein the temperature of said surface of said semiconductor substrate to be used is indirectly controlled by adjusting said heating temperature.
