Abstract: The present invention generally comprises a heated showerhead assembly that may be used to supply processing gases into a processing chamber. The processing chamber may be an etching chamber. When processing gas is evacuated from the processing chamber, the uniform processing of the substrate may be difficult. As the processing gas is pulled away from the substrate and towards the vacuum pump, the plasma, in the case of etching, may not be uniform across the substrate. Uneven plasma may lead to uneven etching. To prevent uneven etching, the showerhead assembly may be separated into two zones each having independently controllable gas introduction and temperature control. The first zone corresponds to the perimeter of the substrate while the second zone corresponds to the center of the substrate. By independently controlling the temperature and the gas flow through the showerhead zones, etching uniformity of the substrate may be increased.

Abstract: In a second tank unit, a controller controls the on/off switching of a water supply solenoid valve so that water is stored in a sub tank within the level of Lu to Ll. At the same time, the controller controls the on/off switching of a pressurizing solenoid valve and a decompressing solenoid valve so that the air pressure in the upper space in the sub tank is maintained at a target value. As a result, regardless of the water level in the sub tank, the back pressure in the tank is maintained at the target value higher than atmospheric pressure. In this state, when a central controller turns on a water spouting solenoid valve, pressured water rapidly spouts from a nozzle. Moreover, a change in the target values of the back pressure promptly changes the height of the spouting water. Accordingly, water spouting can be promptly started/stopped, and the height or size of the spouting water can be readily and smoothly changed.
