The present invention provides a temperature controlled energy transparent window or electrode used to advantage in a substrate processing system. The invention also provides methods associated with controlling lid temperature during processing and for controlling etching processes. In a preferred embodiment the invention provides a fluid supply system for the lid which allows the fluid to flow through a feedthrough and into and out of a channel formed in the window or electrode. The fluid supply system may also mount the window or electrode to a retaining ring which secures the window or electrode to the chamber. In another aspect the invention provides a bonded window or electrode having a first and second plate having a channel formed in the plates so that when the plates are bonded together they form a channel therein through which a temperature controlling fluid can be flowed. An external control system preferably regulates the temperature of the fluid.

A plasma sputtering system is disclosed, along with methods of sputtering and methods of arranging an array of magnets disposed within the sputtering system. An embodiment of the sputtering system includes a vacuum chamber. A rotating magnetron is disposed in the vacuum chamber. A target is positioned between the magnetron and a substrate upon which material from the target is to be deposited. The magnetron includes an array of pairs of oppositely poled permanent magnets. A closed loop magnetic path extends between the pairs of oppositely poled magnets of the array. The magnetic path includes an inturn region proximate to an axis of rotation of the magnetron and at least two (e.g., five) indent regions.
