摘要:
Mixing baths 6A and 6B which temporarily hold chemical agents A and B respectively are disposed. The mixing baths 6A and 6B are each connected with a high-pressure fluid supplying unit 2. For surface treatment using a mixture of the chemical agent A and SCF (processing fluid), SCF is fed under pressure from the high-pressure fluid supplying unit 2 to the mixing bath 6A which already holds the chemical agent A, whereby the chemical agent A dissolves in SCF flowing into the mixing bath 6A and the mixture of the chemical agent A and SCF (processing fluid) is created. As a high-pressure valve (processing fluid introducing valve) 39 is opened, the processing fluid is sent into a pressure vessel 1. This achieves a predetermined surface treatment of a substrate which has been set inside the pressure vessel 1, using the processing fluid.

Provided is a cleaning apparatus for cleaning an object to be treated by contacting the object to be treated with a high pressure fluid of a cleaning composition containing a cleaning component as an essential ingredient. The cleaning apparatus includes high pressure fluid supplying means for supplying the high pressure fluid of the cleaning composition, a high pressure washing vessel for removing unnecessary materials deposited on the object to be treated by contacting the object to be treated with the high pressure fluid of the cleaning composition therein, a storing vessel for storing a waste high pressure fluid of the cleaning composition carrying the unnecessary materials therein, and a sealed structure for sealably housing the high pressure fluid supplying means, the high pressure washing vessel, and the storing vessel therein. The sealed structure has first exhaust means for exhausting the gas remaining in the sealed structure therefrom.

A mixing valve assembly 42 is communicated with a dedicated tank 51D, storing therein a compatibilizer D, via an inlet valve 43 and is also communicated with dedicated tanks 51A-51C via three injection valves, the tanks storing therein auxiliaries A-C respectively. A chemical formulation is prepared by selectively injecting any one(s) of four chemical agents into the mixing valve assembly 42 by way of on-off control of the inlet valve 43 and the injection valves and blending together the injected chemical agents. Then, the chemical formulation is pumped into SCF by a high-pressure pump 45 such that the SCF and the chemical formulation are mixed together to form a process fluid. Thus, the number of components of a high-pressure portion can be reduced to achieve a cost reduction of an apparatus. Furthermore, a pipe line for pumping the chemical agents is simplified.

After subjected to a developing process, a rinsing process and a replacing process in this order in a developing unit 10A, 10B, a substrate W wet with an anti-drying solution is wet-transported to a supercritical drying unit 20 by a primary transport robot 30. The supercritical drying unit 20 performs a high-pressure drying process (supercritical drying process) in a dedicated manner. Accordingly, by virtue of the presence of the anti-drying solution, the substrate W is effectively prevented from becoming air-dry during the transportation of the substrate W.

Disclosed is a high pressure processing method for subjecting a processing object to a high pressure processing using a high pressure fluid. In this method, the high pressure fluid is brought into collision with the surface of the processing object placed in a high pressure processing chamber, and then distributed along the surface of the processing object in an outward direction beyond the processing object.

A method and system for processing a substrate includes performing a wet process by supplying a working liquid to a substrate in a wet processing apparatus, transferring the substrate in a non-dry state from the wet processing apparatus to a drying apparatus, and subjecting the substrate to a supercritical drying by a supercritical fluid in the drying apparatus.
摘要:
Liquid for prevention of substrate drying is supplied into a processing chamber so that a pool of the liquid is created as an anti-drying atmosphere in advance inside a processing chamber, and substrates, as they are dipped in the pool, are kept on stand-by in a substrate board. In this manner, air drying of the substrates which are kept on stand-by is prevented. When the number of the substrates in the substrate board reaches a certain number, the anti-drying atmosphere is removed from the processing chamber, which is followed by introduction of an SCF into the processing chamber and supercritical drying (high pressure drying) of all of the plurality of substrates inside the processing chamber, namely, batch supercritical drying.
摘要:
With respect to any one of processing units, a main transportation path, a developing unit, a dedicated transportation robot and a high-pressure processing unit are disposed linearly in this order in a direction. Hence, even if a processing fluid adhering to a substrate or an evaporant of the processing fluid moves toward the main transportation path while the high-pressure processing unit transports the substrate wet with the processing fluid, there are the processing units located which the processing fluid or its evaporant must arrive at before reaching the main transportation path.
