    Abstract: In a developing method for performing developing treatment of a substrate by supplying a developing solution onto a resist film formed on a surface of the substrate, the present invention controls a zeta potential of the surface of the substrate at a predetermined potential in the same polarity as that of a zeta potential of insoluble substances floating in the developing solution, thereby preventing or reducing the adhesion of the insoluble substances to the resist film and the substrate. This remedies the occurrence of development defects. The adhesion of the insoluble substances to the resist film and the substrate can also be prevented or inhibited by supplying an acid liquid to a liquid on the substrate, or controlling a pH value of the liquid on the substrate to control an absolute value of the zeta potential of the insoluble substances.

  • Patent number: 7530749
    Abstract: A coating and developing system prevents wetting its component units with water when the coating and developing system forms a resist film on a substrate and processes the substrate processed by immersion exposure by a developing process. A substrate having a surface coated with a resist film and processed by immersion exposure is placed on a substrate support device and a liquid detector detects at least the liquid formed a liquid film for immersion exposure and remaining on the surface of the substrate. A decision is made as to whether or not the substrate needs to be dried on the basis of the result of detection made by the liquid detector. If it is decided that the substrate needs to be dried, the substrate is dried by a drying means. Thus wetting the interior of the coating and developing system with water can be prevented. Since only substrates that need to be dried are subjected to a drying process, the coating and developing system is able to operate at a high throughput.

  • Patent number: 6752543
    Abstract: A manifold communicatively connects a plurality of coating processing units with an air conditioning unit. The manifold is formed by branching a common pipe into a plurality of distributing pipes. The air conditioning unit performs temperature control to set air passing through a branch point of the manifold to a temperature slightly lower than a target temperature in processing units. Secondary heaters secondarily heat air passing through joints between the distributing pipes and the processing units to the target temperature thereby supplying accurately temperature-controlled air to processing parts. Air from the air conditioning unit is diverted thereby suppressing the height of the overall apparatus. Thus, a substrate processing apparatus capable of inhibiting the height of the overall apparatus from remarkable increase also when vertically stacking processing parts in multiple stages and supplying temperature-controlled air to the processing parts with sufficient accuracy.

    Abstract: In this developing method and apparatus, a concentration measuring unit 222 picks part of developing fluid in a blending tank 186 to measure the resist concentration by an absorption photometry and feeds the detected resist concentration to a control unit 240. The control unit 240 controls respective valves 210, 212, 216 of a TMAH concentrate solution 200, a solvent pipe 204 and a drain pipe 208 in a manner that the developing fluid in the blending tank 186 has a TMAH concentration corresponding to a measured resist-concentration value to accomplish a constant developing rate, performing component control of the developing fluid. The developing fluid transferred from the blending tank 186 to a supply tank 188 is fed to a developer nozzle DN in a developing section 126 through a developer pipe 224 owing to the drive of a pump 228. Accordingly, even if the developing fluid is reused in the developing process in multiple times, it is possible to make sure of the uniformity in development.

  • Publication number: 20040067453
    Abstract: A method and system of TMAH concentration adjustment. Absorption values A1, Y1 to Ym of a recycled developer solution at wavelength 210 nm and m wavelengths between 220 nm and 250 nm are measured respectively, wherein m is equal to or greater than 2. Y1 to Ym are input to an nth-degree polynomial to generate a wavelength-absorption relationship Y=C1Xn+ . . . +Cn−1X+Cn, wherein X is wavelength, n is a positive integer and C1 to Cn are coefficients of the relationship. Wavelength 210 nm is input into the wavelength-absorption relationship to generate an absorption value Y210. A difference A3 between the A1 and Y210 is calculated as the absorption value of TMAH in the developer solution and A3 is then input to an absorption calibration curve of TMAH at 210 nm to generate a corresponding TMAH concentration. TMAH is then added to provide the corresponding TMAH concentration.

  • Patent number: 6705778
    Abstract: A photographic processing apparatus includes a photographic paper processing bath train. A drier, positioned downstream from the train, heats air and dries the photographic paper. Feeding racks feed the paper in a predetermined travel path which begins on an upstream side of the train, extends therethrough, and ends at the drier. A memory is accessed to estimate expected travel time t1 for passing of the paper through the travel path. The memory is accessed to estimate expected warmup time t2 for warming up the air in the drier to a target temperature T2. A controller compares the time t1 and the time t2, initially starts heating in the drier if the time t2 is longer than the time t1, and starts actuation of the feeding racks when a time difference (t2-t1) elapses after start of the heating to synchronize drier warmup to temperature T2 with paper reaching the drier.

  • Patent number: 6672778
    Abstract: At least two (groups of) sensors forming an insertion detection sensor are offset from each other in the conveyance direction of a photosensitive material. An insertion speed, which is different for each manual insertion event, is obtained based on the time difference when sensors that have been offset from each other detect the leading end of the photosensitive material. The length of the photosensitive material in the conveyance direction thereof is accurately computed based on the insertion speed and other information. By correcting the errors due to the changeable insertion state of the photosensitive material caused by manual insertion by the operator, the process area of the photosensitive material, required for calculating the amount of replenisher to be replenished, is accurately obtained. Therefore, the amount of the replenisher is appropriately determined and the process capacity of the developer or the fixing solution can constantly be maintained at the satisfactory level.
