ABSTRACT:
A vertically oriented thermal processor supports semiconductor wafers within a vertical process chamber within a process tube about which a furnace heater is supported. A base plate support assembly mates with a processing vessel such that the interior surface in proximate fluid adjoining relation with the processing chamber is formed from substantially-inert materials. Additionally, the base plate support assembly includes fluid cooling features that protect seals formed by devices passing through the base plate assembly into the processing chamber for delivery of processing gases and monitoring of thermal conditions therein. Additionally, cooling features are provided in a base plate in order to prevent components from becoming heat sinks or heat sources in relation to the processing chamber.
