  • Patent number: 9502266
    Abstract: An object of the present invention is to provide an epitaxial wafer on which dislocation is preventable even when a LSA treatment is performed in device processes. An epitaxial wafer according to the present invention includes a wafer 11 whose nitrogen concentration is 1×1012 atoms/cm3 or more or whose specific resistance is 20 m?·cm or less by boron doping, and an epitaxial layer 12 provided on the wafer 11. On the wafer 11, if a thermal treatment is performed at 750° C. for 4 hours and then at 1,000° C. for 4 hours, polyhedron oxygen precipitates grow predominantly over plate-like oxygen precipitates. Therefore, in the device processes, plate-like oxygen precipitates cannot be easily formed. As a result, even when the LSA treatment is performed after various thermal histories in the device processes, it is possible to prevent the dislocation, which is triggered by oxygen precipitates, from generating.
