ABSTRACT:
The case of maintainability and component replacement for a vacuum processing chamber is enhanced by providing a vacuum chamber roof assembly whose connection to the vacuum chamber body is through a clamped connection. Accessories needed for the roof assembly, e.g. cooling, heating, RF power, are separately supported and terminated to an accessories supporting cold plate, which is separately mounted such it is easily movable, for example by hinging from the chamber body. The roof of the chamber can then easily be separated from the chamber body and replaced. In an further mode the chamber roof can be easily raised to provide easy access to modular components inside the processing chamber. All components exposed to the plasma in the chamber can be easily accessed and replaced. Moreover, such access is provided without the need to disconnect utilities or instrumentation, since the release of a latch and pivoting the cold plate assembly away from the chamber body upwards is all that is needed to gain access to either the top of the roof of the processing chamber or the inside of the chamber. Chamber roof cooling is provided through a separable connection which is spring clamped to provide a high confidence that uniform thermal conductivity across a clamped joint is maintained.
