Patent ID: 7217323

Claim:
A method for manufacturing a silicon carbide single crystal, the method comprising the steps of: setting a silicon carbide single crystal substrate as a seed crystal in a reactive chamber; introducing a raw material gas including a silicon containing gas and a carbon containing gas into the reactive chamber; growing a silicon carbide single crystal from the silicon carbide single crystal substrate; heating the raw material gas at an upstream side from the silicon carbide single crystal substrate in a gas flow path; keeping a temperature of the silicon carbide single crystal substrate at a predetermined temperature lower than the raw material gas so that the silicon carbide single crystal is grown from the silicon carbide single crystal substrate; heating a part of the raw material gas, which is a non-reacted raw material gas and does not contribute to crystal growth, after passing through the silicon carbide single crystal substrate; and absorbing a non-reacted raw material gas component in the non-reacted raw material gas with an absorber.
