  • Method and apparatus for processing wafer-shaped articles
    Patent number: 11195730
    Abstract: A device for processing wafer-shaped articles comprises a closed process chamber that provides a gas-tight enclosure. A rotary chuck is located within the closed process chamber. A heater is positioned relative to the chuck so as to heat a wafer shaped article held on the chuck from one side only and without contacting the wafer shaped article. The heater emits radiation having a maximum intensity in a wavelength range from 390 nm to 550 nm. At least one first liquid dispenser is positioned relative to the chuck so as to dispense a process liquid onto a side of a wafer shaped article that is opposite the side of the wafer-shaped article facing the heater.
    Type: Grant
    Filed: November 22, 2019
    Date of Patent: December 7, 2021
    Assignee: Lam Research AG

  • Apparatus for processing wafer-shaped articles
    Patent number: 9616451
    Abstract: The harmful effects of accumulating droplets of process liquid on the outer surface of a dispense nozzle are prevented by equipping an apparatus for process wafer-shaped articles with a blow-off block that blows the droplets off the nozzle outer surface before they can coalesce and drop in an uncontrolled manner onto the work piece. The nozzle preferably has a polished and tapered outer surface to aid in blowing off any accumulated droplets of process liquid from the outer surface.
