Title: Low pressure gas phase growing apparatus
Inventor: KIMURA MASAKAZU
IPC: H01L21/285
Filed: 1978-09-04
Abstract: PURPOSE:To lessen both of the loss of reactant gas and the scatter of the film thickness of the gas phase grown layer, by installing the heater for the substrate wafer placed in the reactor tube on the outside of the reactor tube, and by flowing the gas approximately perpendicularly to the axis of the reactor tube. CONSTITUTION:The exhaust gas is exhausted by the vacuum pump through the exhaust gas conduit tube 8 being connected to the gas exhausting chamber 7, whose pressure is kept at constant ranging in 0.2-100 torrs for example. The substrate wafer 9 is placed approximately to the flowing direction of the reactant gas, for instance. The wafer 9 is heated by the resistance heater 10 for example from outside of the reactor tube 2, and is caused to react on the reactant gas being introduced into the tube 2 through the reactant gas feed port 3, under a low pressure; hereby, the gas phase grown layer is formed on the wafer 9. At this apparatus, the distance between the reactant gas feed port 3 and the wafer 9 is short, and besides, plural feed ports 3 are installed; therefore, the scatter of the amount of the reactant materials sticking on the tube wall and also the scatter of thickness of the gas phase grown layer are both lessened.
