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 battery module includes at least two cell assemblies, a module housing having an upper cover formed by a top portion and a first side portion extending downward from a first side edge of the top portion, a first gas passage formed between the first side portion of the upper cover and a first side of the at least two cell assemblies for circulation of gas generated from the at least two cell assemblies, and a flame retardant plate in the first gas passage and extending between the at least two cell assemblies and the module housing, wherein the first side portion of the upper cover is coupled to the flame retardant plate.
