Abstract
Embodiments disclosed herein relate to a substrate processing chamber component assembly with plasma resistant seal. In one embodiment, the semiconductor processing chamber component assembly includes a first semiconductor processing chamber component, a second semiconductor processing component, and a sealing member. The sealing member has a body formed substantially from polytetrafluoroethylene (PTFE). The sealing member provides a seal between the first and second semiconductor processing chamber components. The body includes a first surface, a second surface, a first sealing surface, and a second sealing surface. The first surface is configured for exposure to a plasma processing region. The second surface is opposite the first surface. The first sealing surface and the second sealing surface extend between the first surface and the second surface. The first sealing surface contacts the first semiconductor processing chamber component. The second sealing surface contacts the second semiconductor processing chamber component.
