  • Patent number: 11031262
    Abstract: Implementations disclosed herein describe a bevel etch apparatus within a loadlock bevel etch chamber and methods of using the same. The bevel etch apparatus has a mask assembly within the loadlock bevel etch chamber. During an etch process, the mask assembly delivers a gas flow to control bevel etch without the use of a shadow frame. As such, the edge exclusion at the bevel edge can be reduced, thus increasing product yield.

  • Publication number: 20210066039
    Abstract: One or more embodiments described herein generally relate to a semiconductor processing apparatus that utilizes high radio frequency (RF) power to improve uniformity. The semiconductor processing apparatus includes an RF powered primary mesh and an RF powered secondary mesh, which are disposed in a substrate supporting element. The secondary RF mesh is positioned underneath the primary RF mesh. A connection assembly is configured to electrically couple the secondary mesh to the primary mesh. RF current flowing out of the primary mesh is distributed into multiple connection junctions. As such, even at high total RF power/current, a hot spot on the primary mesh is prevented because the RF current is spread to the multiple connection junctions. Accordingly, there is less impact on substrate temperature and film non-uniformity, allowing much higher RF power to be used without causing a local hot spot on the substrate being processed.
