More Information
Summary:An exposure apparatus for transferring a pattern from a reticle to a workpiece, a pellicle being positioned near the reticle, includes a heat transfer frame, an illuminator, and a temperature controller. The heat transfer frame is configured to be positioned near the pellicle, the heat transfer frame defining a beam aperture. The illuminator directs a beam through the beam aperture and the pellicle at the reticle. The temperature controller controls the temperature of the heat transfer frame to control the temperature of the pellicle. The illuminator can direct the beam from a beam source, such as an EUV beam source. Additionally, the temperature controller can cryogenically cool the heat transfer frame.
