  • Patent number: 6709531
    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: 20040043310
    Abstract: A processing method for selectively reducing or removing the region to be exposed with energy ray in a film formed on a substrate, comprising relatively scanning a first exposure light whose shape on the substrate is smaller than the whole first region to be exposed against the whole first region to be exposed to selectively remove or reduce the first region to be exposed, and exposing a whole second region to be exposed inside the whole first region to be exposed with a second exposure light to selectively expose the whole second region to be exposed.

  • Publication number: 20040029026
    Abstract: There is disclosed a substrate treating method comprising supplying a treating solution onto a substrate, and continuously discharging a first cleaning solution to the substrate from a first discharge region disposed in a nozzle, while moving the nozzle and substrate with respect to each other in one direction, wherein a length of a direction crossing at right angles to the direction of the first discharge region is equal to or more than a maximum diameter or longest side of the substrate, the nozzle continuously spouts a first gas to the substrate from a first jet region, and the length of a direction crossing at right angles to the direction of the first jet region is equal to or more than the maximum diameter or longest side of the substrate.

  • Publication number: 20030219660
    Abstract: In a pattern forming method, a photoresist layer is formed on the major surface of a to-be-processed substrate, then exposed to light to form a desired latent pattern thereon, and developed into a resist pattern. An abnormality in a size or shape of the resist pattern is detected, and is corrected. Correction is performed by irradiating the resist pattern with light of a wavelength which the photoresist layer can absorb, and changing the shape of the resist pattern.

  • 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.

  • Publication number: 20020155391
    Abstract: There is disclosed, as an aspect, a method of forming a pattern which comprising coating a photosensitive resist film on a surface of substrate, subjecting the photosensitive resist film to an exposure process, coating an oxidizing liquid having an oxidative effect on a surface of the photosensitive resist film that has been subjected to the exposure process to thereby perform a pretreatment wherein the surface of the resist film is caused to oxidize by the oxidizing liquid to form an oxide layer thereon, feeding a developing solution to the photosensitive resist film whose surface has been oxidized to thereby perform a development of the resist film, and feeding a rinsing solution to a surface of the substrate to wash the substrate.
