Abstract

A reactor, suitable for CVD processes, which presents a high aspect ratio to reactant gasses, is described. Substrates are mounted on oppositely disposed susceptors in a vertical chimney-type reactor. Means are provided to rotate the susceptors about an axis perpendicular to gas flow. Side-loading or top-loading mechanisms are provided for loading and unloading the susceptors through a gate valve. A diffuser below the reaction zone adjusts the gas flow into the reaction zone.
