Patent number: 10121682Abstract: A purge ring for providing a gas to a wafer processing chamber includes an inlet ring wall defining a ring hole space. An outer perimeter of the inlet ring wall is elliptical. An outer perimeter of the ring hole space is circular. The inlet ring wall is a continuous structure surrounding the ring hole space. An inlet baffle formed within the inlet ring wall surrounds at least 180 degrees of the outer perimeter of the ring hole space. An inlet plenum arranged in a first end of the inlet ring wall provides the gas to the ring hole space through the inlet baffle. An exhaust channel is formed within the inlet ring wall in a second end of the inlet ring wall. An exhaust outlet hole arranged in the second end of the inlet ring wall exhausts the gas out of the ring hole space via the exhaust channel.Type: GrantFiled: June 3, 2016Date of Patent: November 6, 2018Assignee: Novellus Systems, Inc.Inventors: Eugene Smargiassi, Stephen Yu-Hong Lau, George D.

Patent number: 10020197Abstract: 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: GrantFiled: May 20, 2015Date of Patent: July 10, 2018Assignee: Novellus Systems, Inc.Inventors: Lisa Gytri, Jeff Gordon, James Lee, Carmen Balderrama, Joseph Brett Harris, Eugene Smargiassi, Stephen Yu-Hong Lau, George D.
