  • Patent number: 10112210
    Abstract: At the time of initiating coating, when a first end of an ejecting port of a coating nozzle is located at one end of a peripheral edge of a wafer, the wafer and the coating nozzle are relatively moved by a moving mechanism while exposing a coating liquid from the ejecting port. During the coating, the wafer and the coating nozzle are relatively moved by the moving mechanism while the coating liquid ejected from the ejecting port is in contact with the wafer, to coat the coating liquid on the wafer. At the time of finishing the coating, when a second end of the ejecting port is located at the other end of the peripheral edge of the wafer, the wafer and the coating nozzle are relatively moved by the moving mechanism while exposing the coating liquid from the ejecting port.

  • Patent number: 9623435
    Abstract: Disclosed is a substrate processing apparatus. The substrate processing apparatus includes a moving mechanism that moves a wafer in a horizontal direction, coating sections that eject the coating liquid to the wafer, and dry sections that dries the coating liquid, and a controller that controls the drying sections, the coating sections, and the moving mechanism. In each coating section, the wafer is moved in the horizontal direction while causing the coating liquid to be in contact with the wafer so that the coating liquid is coated on the entire surface.

  • Patent number: 8192796
    Abstract: In the present invention, a holding table incorporating a heater is provided, for example, in a treatment container of a planarization unit. A pressing plate having a lower surface formed flat is disposed above the holding table. The pressing plate is movable in the vertical direction and can lower to the holding table to press a resist film on the substrate from above. The pressing plate intermittently presses the upper surface of the resist film to planarize the upper surface while the heater is heating the substrate on the holding table at a predetermined temperature to dry the resist film. According to the present invention, a coating film applied on the substrate can be sufficiently planarized and dried.
