    摘要: Embodiments of the present invention provide structures for reducing erosion of a slit valve utilized in the fabrication of semiconductor devices. Specifically, non-metallic slit valve components such as a compressible sealing member and a barrier that assist in sealing the valve closure against the slit valve seat, are positioned on the valve seat rather than on the valve closure. This orientation removes the seal and the seal barrier from the direct line of sight of the plasma within the processing chamber, reducing exposure of the sealing member and seal barrier slit valve components to erosion and thereby extending the lifetime of the valve.
