Abstract:
A temperature controlled loadlock chamber for use in semiconductor processing is provided. The temperature controlled loadlock chamber may include one or more of an adjustable fluid pump, mass flow controller, one or more temperature sensors, and a controller. The adjustable fluid pump provides fluid having a predetermined temperature to a temperature-controlled plate. The mass flow controller provides gas flow into the chamber that may also aid in maintaining a desired temperature. Additionally, one or more temperature sensors may be combined with the adjustable fluid pump and/or the mass flow controller to provide feedback and to provide a greater control over the temperature. A controller may be added to control the adjustable fluid pump and the mass flow controller based upon temperature readings from the one or more temperature sensors.
