<p>A lid assembly for a narrow-gap magnetically enhanced reactive ion etch (MERIE) chamber. The lid assembly has a lid and a liner. Both pieces are substantially U-shaped and interfit such that the interface between them extends outside the chamber. A blocker plate is situated in a recess between a lower surface of the lid and an upper surface of the liner. The blocker plate is concave in shape so that a downward bow of the lid does not exert a stress on the blocker plate. The novel lid assembly is more leak resistant, requires less cleaning time and is cheaper than a design that utilizes a moving pedestal.</p> |
