摘要： 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.

摘要： 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.

摘要： A method for removing species from a substrate includes arranging a purge ring in a chamber proximate to a pedestal. The purge ring includes an inlet portion and an exhaust portion. The inlet portion defines an inlet plenum and an inlet baffle. The inlet baffle includes a continuous slit that is substantially continuous around a peripheral arc not less than about 270°. The exhaust portion includes an exhaust channel that is located substantially opposite the inlet baffle. The method further includes supplying ozone to the inlet plenum; at least partially defining a ring hole space having a periphery using the inlet portion and the exhaust portion; conveying gas from the inlet plenum into the ring hole space using the inlet baffle; conveying gas and other matter out of a purge space using the exhaust portion; and inhibiting deposition of material evolved from the substrate during curing using the purge ring.
