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 5):
A reaction tube for use in a substrate processing apparatus, comprising:\n a cylindrical inner tube having a closed end; and a cylindrical outer tube having a closed end, wherein the cylindrical outer tube includes an exhaust port which is in fluid communication with a gap between the cylindrical inner tube and the cylindrical outer tube and configured to exhaust an internal atmosphere of the reaction tube, wherein the cylindrical inner tube includes a plurality of inlet ports and an outlet port, the plurality of inlet ports being configured to inwardly guide gases supplied from a plurality of gas nozzles arranged in the gap, a plurality of partitions configured to surround each of the plurality of gas nozzles or to separate the plurality of gas nozzles from each other, and the outlet port being configured to be opened at a position facing the inlet port and configured to guide the internal atmosphere to the gap, and wherein at least one of the plurality of partitions, which corresponds to one of the plurality of gas nozzles, has an opening formed to allow an inert gas supplied from the portion of the plurality of gas nozzles to flow into the gap,
