| 摘要 |
In some embodiments, a method for cooling a substrate upon a biasable cooling pedestal for supporting a substrate during deposition within a plasma vapor deposition chamber may include a supplying a low pressure inert gas from the shaft of a liquid-chilled pedestal to flow through one or more channels within grooved a metal substrate support and a liquid-chilled body. By maintaining a cooling gas supply at a pressure well below that which may displace the weight of the substrate, the gas may enable even heat transfer between the cooling pedestal and the substrate to cool the substrate during deposition without the use of electrical or mechanical mechanisms for clamping the substrate in place.
