    Abstract: A system for degassing substrates provides reduced infrared sources in a degas chamber. In some embodiments, the system includes a degas chamber with a microwave source and an infrared temperature sensor positioned in a bottom of the degas chamber, at least one hoop with an annular shape that is configured to support or lift a substrate and is formed from at least one first material that is opaque to microwaves and has an emissivity of 0.1 or less, and at least one actuator with a movable vertical shaft. Each of the at least one actuator is attached under one of the hoops at an outer perimeter of the hoop. The portion of the movable vertical shaft that is exposed to microwaves from the microwave source in the degas chamber is formed from at least one second material that is opaque to microwaves and has an emissivity of 0.1 or less.
