  • Publication number: 20150056108
    Abstract: Porogen accumulation in a UV-cure chamber may be reduced by removing outgassed porogen by flowing a purge gas across a window through which a wafer is exposed to UV light. Porogens in the purge gas stream may, as they flow through the chamber and into an exhaust baffle, deposit on surfaces within the chamber, including on the exhaust baffle. The exhaust baffle may have particular features that cause such porogen deposition to be more uniformly distributed across the exhaust baffle, thus reducing the amount of time that may be required to fully clean the baffle of accumulated porogens during a cleaning process.
