Abstract:
1. A substrate processing apparatus comprising: a reaction tube having a processing chamber provided therein to process a substrate; an induction heating unit installed outside of the reaction tube to receive the reaction tube, wherein the induction heating unit is configured to electromagnetically induction-heat the processing chamber by generating a magnetic field; an accommodation tube installed outside of the induction heating unit to receive the induction heating unit, wherein the accommodation tube encloses the reaction tube and the induction heating unit in an air-tight manner; a shielding unit made of a conductive material installed to surround an outside of the accommodation tube; and an inert gas supply unit installed in a gap between the reaction tube and the accommodation tube where the induction heating unit is installed, wherein the inert gas supply unit is configured to supply an inert gas into the gap.
