    摘要: A processing system utilizing a supercritical fluid for treating a substrate is described as having a pump for recirculating the supercritical fluid over the substrate. For various applications in supercritical fluid processing, the fluid temperature for the treatment process can elevate above the temperature acceptable for safe operation of the pump. Therefore, in accordance with one embodiment, a fraction of supercritical fluid from the primary recirculating flow of supercritical fluid over the substrate is circulated from the pressure side of the pump, through a heat exchanger to lower the temperature of the supercritical fluid, through the pump, and it is returned to the primary flow on the suction side of the pump. In accordance with yet another embodiment, supercritical fluid is circulated through the pump from an independent source to vent.

    摘要: In a high pressure processing system configured to treat a substrate, a flow measurement device is utilized to determine a flow condition in the high pressure processing system. The flow measurement device can, for example, comprise a turbidity meter. The flow parameter can, for example, include a volume flow rate or a time to achieve mixing of a process chemistry within a high pressure fluid used to treat the substrate.

    摘要: A method and system for passivating a processing chamber is provided, whereby the processing chamber is exposed to one or more cycles of citric acid, or nitric acid. The processing chamber is fabricated, for example, from stainless steel. Each cycle may be performed at a pressure greater than atmospheric pressure, or a temperature greater than 20 degrees centigrade, or both.
