  • Patent number: 9214363
    Abstract: Disclosed is a technique for preventing a water-repellent protective film formed on a resist film from peeling off during immersion exposure. A resist film is formed on the front surface of a substrate and then the peripheral edge portion of the resist film is removed. Before forming a water-repellent protective film onto the resist film, an adhesion-improving fluid, preferably hexamethyldisilazane gas, for improving the adhesion of the water-repellent protective film, is supplied to the region from which the resist film is removed.

  • Publication number: 20150318193
    Abstract: A substrate liquid treatment apparatus comprises a chuck (13) that holds and rotates a wafer, a back surface purging nozzle (15) that discharges a purge gas toward the back surface of the wafer, and a periphery purging nozzle 16 that discharges the purge gas onto the back surface of the wafer. The back surface purging nozzle has a slit-like opening part extending from a central side to a peripheral side of the substrate in a plan view. Vertical distance between the slit-like opening part and the substrate held by the substrate holding unit increases as approaching an end of the opening part on the central side of the substrate. The periphery purging nozzle discharges the purge gas, toward a central part of the substrate, toward a region on the back surface of the substrate, which region is located radially outside an end of the slit-like opening part of the back surface purging nozzle and radially inside an peripheral edge of the substrate.

  • Patent number: 9052610
    Abstract: A coating and developing system for forming a resist film on a substrate by coating the substrate with a liquid resist and developing the resist film after the resist film has been processed by immersion exposure that forms a liquid layer on the surface of the substrate is capable of reducing difference in property among resist films formed on substrates. The coating and developing system includes: a cleaning unit; a carrying means; and a controller. A set time interval is determined such that the substrate is subjected to the immersion exposure process after contact angle drop rate at which contact angle between the cleaning liquid and a surface of the substrate drops has dropped from an initial level at the wetting time point when the surface of the substrate is wetted with the cleaning liquid to a level far lower than the initial level.

  • Publication number: 20150036109
    Abstract: A developing method includes: horizontally holding an exposed substrate by a substrate holder; forming a liquid puddle on a part of the substrate, by supplying a developer from a developer nozzle; rotating the substrate; spreading the liquid puddle on a whole surface of the substrate, by moving the developer nozzle such that a supply position of the developer on the rotating substrate is moved in a radial direction of the substrate; bringing, simultaneously with the spreading of the liquid puddle on the whole surface of the substrate, a contact part into contact with the liquid puddle, the contact part being configured to be moved together with the developer nozzle and having a surface opposed to the substrate which is smaller than the surface of the substrate. According to this method, an amount of liquid falling down to the outside of the substrate can be inhibited. In addition, since the rotating speed of the substrate can be decreased, spattering of the developer can be inhibited.

  • Publication number: 20150027492
    Abstract: There are provided first and second cleaning members which are configured to clean a central zone in a rear surface of a wafer when the wafer held by an absorption pad is horizontally held, and configured to clean a peripheral zone in the rear surface of the wafer when the wafer is held by the spin chuck. Due to the provision of the first and second cleaning members, detergency can be improved as compared with a case in which only one cleaning member is used. The first and second cleaning members are configured to be horizontally turned by a common turning shaft. When the central zone in the rear surface of the wafer is cleaned, the turning shaft is located to be overlapped with the wafer. Since the turning shaft is located by using the moving area of the wafer, a size of an apparatus can be reduced.
