  • 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.

  • Patent number: 11136665
    Abstract: Embodiments of the invention contemplate a shadow ring that provides increased or decreased and more uniform deposition on the edge of a wafer. By removing material from the top and/or bottom surfaces of the shadow ring, increased edge deposition and bevel coverage can be realized. In one embodiment, the material on the bottom surface is reduced by providing a recessed slot on the bottom surface. By increasing the amount of material of the shadow ring, the edge deposition and bevel coverage is reduced. Another approach to adjusting the deposition at the edge of the wafer includes increasing or decreasing the inner diameter of the shadow ring. The material forming the shadow ring may also be varied to change the amount of deposition at the edge of the wafer.
