Patent ID: 7314519

Claim:
A vapor-phase growth apparatus comprising: a reaction furnace which is hermetically closable, a wafer container which is disposed in the reaction furnace, for disposing a wafer at a predetermined position, a gas supply member for supplying a source gas toward the wafer, and a heating member for heating the wafer, wherein the apparatus is designed to form a grown film on a front surface of the wafer by supplying the source gas in a high temperature state while the heating member heats the wafer in the reaction furnace through the wafer container, the wafer container comprises a heat flow control section having a space for disposing the wafer, and a heat flow transmitting section joined to the heat flow control section, for transmitting heat to the wafer disposed in the space, the wafer is disposed on the heat flow transmitting section and disposed in the space of the heat flow control section, a heat resistance R g at a flat or curved surface where the heat flow control section and the heat flow transmitting section are close to each other is uniform, and a ratio R 2 /R 1 is not less than 0.8 to not more than 1.2, where R 1 is a heat resistance for a heat transfer route from a rear surface of the heat flow transmitting section to the front surface of the wafer disposed on the heat flow transmitting section, and R 2 is a heat resistance for a heat transfer route from the rear surface of the heat flow transmitting section to a front surface of the heat flow control section.
