  • Publication number: 20040159398
    Abstract: In this disclosure, air flow is formed above chemical liquid film and a move of the chemical liquid is generated by making the air flow into a contact with the surface of chemical liquid. Further, a negative pressure is generated in a space between a processing object substrate and a plate by rotating the plate. Consequently, uniformity of processing of chemical liquid is improved, so that liquid removing step can be carried out effectively. As a result, yield rate of chemical liquid treatment can be improved.

  • Publication number: 20040126501
    Abstract: Disclosed is a film-forming method, comprising dispensing from a dispenser nozzle a coating solution, which is prepared by adding a solid component to a solvent and controlled to be spread on the substrate in a predetermined range, onto a target substrate to be processed while relatively moving the dispenser nozzle and the target substrate so as to form a liquid film on the entire surface of the target substrate, and arranging a sucking nozzle above and apart from the target substrate such that the sucking nozzle is not in contact with the surface of the liquid film so as to permit the sucking nozzle to suck the solvent vapor right under the sucking nozzle while moving the sucking nozzle relative to the target substrate, thereby removing the solvent from the liquid film and, thus, forming a coated film.

  • Publication number: 20030202238
    Abstract: An ultraviolet microscope comprises an observation device which observes a specimen with ultraviolet light; a gas supply device which, during the observation with ultraviolet light, supplies an inert gas to surroundings of the specimen; and a timing control device which controls supply timing of the inert gas by the gas supply device, and the timing control device controls the gas supply device so as to cause preliminary supply of the inert gas before the observation of the specimen with ultraviolet light, and also so as to cause regular supply of the inert gas at least during the observation of the specimen with ultraviolet light.

  • Patent number: 6372413
    Abstract: A TMAH developer is applied to a to-be-processed substrate that has an organic resist film formed thereon and having an LSI pattern created by exposure, thereby developing the resist pattern, followed by rinsing processes in which, while the substrate is being rotated at 500 rpm, ozone water containing 3-ppm ozone gas is applied to the substrate for fifteen seconds, thereby decomposing organic matter sticking to the exposed surface of the substrate, and then hydrogen water containing 1.2-ppm hydrogen gas is applied to the substrate for fifteen seconds, with the substrate rotated at 500 rpm, thereby removing the decomposed organic matter from the substrate.
