Title: Method for producing silicon carbide single crystal
Inventor: KONDO HIROYUKI
IPC: C30B29/36
Filed: 1999-11-29
Abstract: PROBLEM TO BE SOLVED: To prevent thermal etching of a coating material for covering a silicon carbide crystal substrate and carbonization of a silicon carbide crystal substrate. SOLUTION: When heat treatment is carried out, an atmosphere in a crucible 1 is adjusted to an atmosphere of silicon vapor pressure higher than a saturated vapor pressure of silicon in silicon carbide at a heat treatment temperature during the heat treatment. For example, (the vapor pressure of) the silicon vapor pressure atmosphere in the crucible 1 in the heat treatment can be raised by arranging a silicon-containing material 6 in the crucible 1. When the silicon vapor pressure atmosphere is made higher than the silicon saturated vapor pressure, namely in a state rich in silicon, sublimation of silicon from the coating material 5 can be prevented and micropipe defects 4a can be surely covered with the coating material 5 in the heat treatment.  Consequently, the coating material 5 can be prevented from being thermally etched and the silicon carbide crystal substrate 4 can be prevented from being carbonized.
