Classification: CPC C  H  F | IPC C  F  H

Claim 0:
1. A device for manufacturing a semiconductor substrate comprising:
a main container that accommodates a semiconductor substrate;
a high melting point container; and
a heating furnace having a heating chamber that accommodates the main container and the high melting point container,
wherein the heating furnace includes a heating source in a direction intersecting with main surface of the semiconductor substrate to be arranged in the heating chamber,
wherein the main container is made of a material containing all atomic species constituting the semiconductor substrate,
wherein the high melting point container comprising a gaseous species vapor pressure space which accommodates the main container and in which a vapor pressure environment of a gaseous species of an atomic species constituting the semiconductor substrate is formed,
wherein an inside of the main container is exhausted through the gaseous species vapor pressure space.
