Abstract:
1. A substrate processing apparatus comprising: a processing chamber for processing a substrate mounted on a substrate mounting unit; a supply unit for supplying processing gas to the processing chamber; an exciting unit for exciting supplied processing gas; an exhaust unit for exhausting the atmosphere in the processing chamber; a support unit that supports the substrate mounting unit; a rotational drive unit for horizontally rotating the support unit; and a coolant supply/discharge unit that is connected with the lower end of the support unit through a connecting unit and is not horizontally rotated, wherein the substrate mounting unit has a coolant circulation path therein, wherein the support unit includes a first coolant supply path for supplying coolant to the coolant circulation path and a first coolant discharge path for discharging coolant from the coolant circulation path, wherein the coolant supply/discharge unit includes a second coolant supply path and a second coolant discharge path, wherein the connecting unit connects together the first coolant supply path and the second coolant supply path and connects together the first coolant discharge path and the second coolant discharge path, and wherein the connecting unit is provided outside the processing chamber.
