Abstract:
1. A system for cooling coated semiconductor substrates, said system comprising: a chamber for receiving at least one coated semiconductor substrate; a high pressure fluid reservoir that vents cooling fluid into the chamber; a coupling coupled to the chamber and the high pressure fluid reservoir for placing the chamber in fluid communication with the high pressure fluid reservoir, the coupling comprising a filter to exclude contaminate particles from the fluid; an inlet valve attached to the coupling for controlling a flow of cooling fluid between the high pressure fluid reservoir and the chamber, wherein the pressure drop across the inlet valve affects the cooling fluid temperature and is at least about 10 bar depending on independent adjustments made to the inlet valve and outlet valve; a controller coupled to the inlet valve that selectively controls the inlet valve to optimize the pressure drop across the inlet valve separately and apart from the outlet valve by ma adjustments to each independently of the other based on calculated temperature readings of the respective valves.
