Abstract: A wafer manufacturing method, an epitaxial wafer manufacturing method, and a wafer and epitaxial wafer manufactured thereby, are provided. The wafer manufacturing method enables the manufacture of a wafer with a low density of micropipe defects and minimum numbers of particles and scratches. The epitaxial wafer manufacturing method enables the manufacture of an epitaxial wafer that has low densities of defects such as downfall, triangular, and carrot defects, exhibits excellent device characteristics, and improves the yield of devices.

Abstract: A structure for mounting a high-mounted stop lamp. An upper housing and a lower housing are not provided. A stop lamp having a reflector and a lens is placed in a space defined by a cover part of a tailgate trim which is formed to have a configuration for receiving the stop lamp therein. A pair of mounting sections protrudes from left and right portions of a rear wall of the reflector. By the medium of the pair of mounting sections, the reflector is locked by bolts to a tailgate inner panel which is positioned above the reflector and is coupled by clips to the cover part of the tailgate trim which is positioned below the reflector.
