  • Patent number: 11177131
    Abstract: Porogen accumulation in a UV-cure chamber is reduced by removing outgassed porogen through a heated outlet while purge gas is flowed across a window through which a wafer is exposed to UV light. A purge ring having specific major and minor exhaust to inlet area ratios may be partially made of flame polished quartz to improve flow dynamics. The reduction in porogen accumulation allows more wafers to be processed between chamber cleans, thus improving throughput and cost.
    Type: Grant
    Filed: July 6, 2018
    Date of Patent: November 16, 2021
    Assignee: Novellus Systems, Inc.
    Inventors: Lisa Marie Gytri, Jeff Gordon, James Forest Lee, Carmen Balderrama, Joseph Brett Harris, Eugene Smargiassi, Stephen Yu-Hong Lau, George D. Kamian, Ming Xi
