摘要:
A process system produces a process liquid of a predetermined concentration in a blending tank by blending solutions respectively supplied from a plurality of solution supply sources, supplies the process liquid to a supply tank to store therein the process liquid, and supplies the process liquid from the supply tank to a process liquid discharge port. In this process system, whether a concentration of the process liquid in the supply tank has changed or not is judged. When it is judged that the concentration of the process liquid in the supply tank has changed, the process liquid is additionally supplied from the blending tank to the supply tank, or the solution is directly supplied from the solution supply source to the supply tank, so as to maintain the concentration of the process liquid.

A substrate processing vessel has a vessel body 100 and a cover 130 hermetically joined to the vessel body 100. The vessel body 100 is provided with a plurality of substrate support rods 102. Each of the support rods 102 has a shank 103 and a head 104 having a diameter greater than that of the shank 103 and attached to the upper end of the shank 103. The shanks 103 penetrate the vessel body 100 and project downward from the vessel body 100. When each substrate support rod 102 is lowered to its lower position, the head 104 is seated hermetically on a part, around the open upper end of a through hole 108 through which the shank 103 is inserted, of the vessel body 100. When each substrate support rod 102 is raised to its upper position, a space of a big thickness capable of receiving a wafer carrying arm 14a is formed between the upper surface of the vessel body 100 and a wafer W supported on the substrate support rods 102. A processing space defined by the substrate processing vessel may be very thin, the amount of a processing fluid necessary for processing the wafer W can be reduced and throughput can be increased.

The substrate processing system has an ozone generator that generates and supplies an ozone-containing gas to plural or N (N is a natural number not less than 2) ozone process units. The ozone generator has capacity of supplying the first processing fluid to only N−n of the first processing units simultaneously at respective supply rates each in accordance with a demand for appropriately performing the first process in each of the first processing units, where n is a natural number and N−n is not less than 2. A controller that controls a timing of loading of the substrate into the ozone process units by the conveyer so as to avoid a case where more than N−n of the first processing units are simultaneously carrying out the first treatment each using the first processing fluid, where n is a natural number and N−n is not less than 2.

A steam generator 40′ provided in a substrate processing apparatus includes a tank 301 having a hollow cylindrical member 302 formed of a composite of PTFE and PFA and a pair of side wall plates 303 connected to the opposite ends of the cylindrical member 302. The tank 301 is surrounded by a shell 305 of an aluminum alloy to prevent deformation of the tank due to internal pressure of the tank. A heater 308 is attached to the outer surfaces of the plate members 307 of the shell 305. The shell 305 restrains the tank 301 and compresses elastic sealing members 305 to sealingly engage the cylindrical member 302 and the side wall plate 303 with each other.

In a pneumatically driven liquid supply apparatus comprising a circulation pump 26 or constant-volume pump 34 for supplying a washing liquid or chemical to a washing tank 20 for semiconductor wafers used during the fabrication of semiconductor devices; an electromagnetic switching valve 51 and a pressure regulator 52 that configure an air-pressure adjustment means 50 are connected to an air source 60; and air supply pipelines 41a, 41b, 41d, and 41e are each connected to the air-pressure adjustment means 50, the circulation pump 26 and the constant-volume pump 34. A leakage sensor 70 is interposed within each of the air supply pipelines 41a, 41b, 41d, and 41e between the air-pressure adjustment means 50 and the circulation pump 26 or constant-volume pump 34, so that any liquid that flows backward through the circulation pump 26 or the constant-volume pump 34 and into the air supply pipeline 41a, 41b, 41d, or 41e is detected by the leakage sensor 70. This makes it possible to prevent damage or halting of the functions of the air-pressure adjustment means due to liquid flowing into the air supply pipelines via one of the pumps.
