    Abstract: The present disclosure provides a multifunction chamber having a multifunctional shutter disk. The shutter disk includes a lamp device, a DC/RF power device, and a gas line on one surface of the shutter disk. With this configuration, simplifying the chamber type is possible as the various specific, dedicated chambers such as a degas chamber, a pre-clean chamber, a CVD/PVD chamber are not required. By using the multifunctional shutter disk, the degassing function and the pre-cleaning function are provided within a single chamber. Accordingly, a separate degas chamber and a pre-clean chamber are no longer required and the overall transfer time between chambers is reduced or eliminated.
