Abstract:
A substrate processing apparatus includes: a reaction tube including inner and outer tubes installed to surround the inner tube; a substrate holder for holding substrates in a vertical direction; gas nozzles installed in a gap between the outer and inner tubes and having supply holes from which a gas is supplied toward an inlet port of the inner tube; a gas supply system for feeding gases to the reaction tube though the gas nozzles; an outlet port formed in the inner tube to flow out the gas; a discharge port for discharging the gas; a discharge part for discharging the gas staying in the gap from the discharge port; and a controller for controlling the gas supply system to supply a precursor gas and an inert gas and for causing the discharge part to purge the gas staying in the gap with the inert gas.

Claim (Index 1):
A substrate processing apparatus, comprising:\n a reaction tube including a cylindrical inner tube and a cylindrical outer tube installed so as to surround the cylindrical inner tube; a substrate holder accommodated in the cylindrical inner tube and configured to hold a plurality of substrates in a vertical direction; gas nozzles installed in a gap between the cylindrical outer tube and the cylindrical inner tube to extend along the vertical direction, and having a plurality of supply holes formed in the vertical direction, from which a gas is supplied toward an inlet port formed in the cylindrical inner tube; a gas supply system configured to feed gases to the reaction tube though the gas nozzles; an outlet port formed in the cylindrical inner tube and configured to allow the gas supplied to the cylindrical inner tube to flow out therethrough; a discharge port formed in the cylindrical outer tube and configured to discharge the gas flowing out from the outlet port to outside of the reaction tube; a discharge part configured to discharge the gas staying in the gap from the discharge port; and a controller configured to control the gas supply system to supply a precursor gas and an inert gas so that a film is formed on each of the plurality of substrates, and configured to cause the discharge part to purge the gas staying in the gap with the inert gas, so that the gas staying in the gap is discharged.
