Abstract:
1. A substrate processing apparatus, comprising: a processing chamber; a plurality of process areas provided in the processing chamber, each of the process areas being configured to supply a reaction gas to process a substrate; a turntable provided in the processing chamber and configured to rotate such that the substrate placed on an upper surface of the turntable passes through the process areas in sequence; a gas nozzle provided in one of the process areas and extending in a direction that intersects with a rotational direction of the turntable, the gas nozzle having discharge openings that are arranged along a length of the gas nozzle and configured to discharge the reaction gas; a separating area provided between the process areas in the rotational direction and configured to supply a separation gas to separate atmospheres of the process areas; and a cover part configured to cover the gas nozzle and cause the reaction gas supplied from the gas nozzle to remain around the gas nozzle, the cover part including wherein the cover part further includes a guide surface configured to guide the separation gas flowing from the upstream side in the rotational direction to flow over a lower part of the upstream side wall to a space above the upper wall; wherein a distance between the gas nozzle and the upstream side wall is greater than or equal to 8 mm, wherein the outer wall has a slit portion into which the gas nozzle is inserted, said slit portion being on the downstream side of the cover part, wherein the inner wall extends between the upstream and downstream walls without a slit.
