Process for growing silicon carbide single crystal and device for the same

Abstract

Provided is a method for manufacturing a silicon carbide single crystal using a solution process including coming a seed crystal substrate for growing silicon carbide into contact with a Si—C alloy solution including at least one additive metal and growing the silicon carbide single crystal on a seed crystal for growing silicon carbide, including feeding a silicon feedstock into an alloy solution when a molar ratio of Si and the additive metal is lower than an initially set value as the reaction progresses. The method increases a crystal growth speed, maintains the growth speed, and prevents the growth from unwillingly stopping when the silicon carbide single crystal is manufactured using a solution growth process.
