Abstract

A rapid thermal process reactor includes a vessel having a dome assembly. The vessel bounds a reactor chamber for rapid thermal processing of one or more substrates. The dome assembly includes a low profile dome and a flange surrounding and abutting the low profile dome. The flange includes a top surface; a bottom surface, removed from and opposite the top surface; an outer circumferential edge surface connecting the top surface and the bottom surface; and an inner edge surface, opposite and removed from said outer circumferential edge, including a portion abutting said low profile dome. The rapid thermal process reactor also includes a radiant heat source; a gas ring mounted about a sidewall of the vessel; a gas ring shield mounted as part of the sidewall of the vessel; a clamp ring to clamp the dome assembly in place; and a clamp ring shield mounted on the clamp ring.
