Abstract:
1. A substrate processing apparatus comprising: a substrate loading/unloading unit that transfers a substrate accommodated in a carrier; a substrate transfer chamber communicating with the substrate loading/unloading unit via a substrate loading/unloading port; a plurality of substrate processing chambers arranged along the substrate transfer chamber; a substrate transfer device provided in the substrate transfer chamber and configured to transfer the substrate between the substrate loading/unloading unit and the substrate processing chambers; and a first clean air flowing unit that includes an air supply unit and an air exhaust unit and allows clean air to flow in the substrate transfer chamber, wherein the first clean air flowing unit generates a flow of clean air in an arrangement direction of the plurality of substrate processing chambers within the substrate transfer chamber, the substrate loading/unloading port and the air supply unit are provided at a first sidewall of the substrate transfer chamber, the air supply unit is provided above the substrate loading/unloading port, and the air exhaust unit is provided at a second sidewall which is opposite to the first sidewall.
