    Abstract: A procedure for the installation of clean room processing tools which require rough pumping equipment located in areas outside of the clean room. Instead of simultaneously installing and testing the pumping equipment and the processing tool, the pumping equipment is installed first along with its associated support services. Foreline piping, terminating in the proximity of the processing tool vacuum port is also installed and capped off at this time. Functional testing and qualification of the rough pumping equipment is done and then the processing tool is moved into place and connected to the pumping line on the clean room floor. This independent and sequential installation procedure reduces perturbations of on-going manufacturing activity in the clean room area and also minimizes the risk of costly damage to the processing tool by faulty, un-tested, pumping equipment. In addition, since the rough pumping equipment can be procured and installed before hand, time can be saved by getting the processing tool on-line faster.

    Abstract: A furnace system for preventing gas leakage is disclosed. The furnace system includes a bottom board for holding a furnace tube. A gas injection device is connected to the furnace tube at a first port for injecting reaction gas into the furnace tube. An exhaust subsystem is connected to the furnace tube at a second port. The exhaust subsystem has a first node, a second node, a third node and a fourth node. A vacuum seal is connected to the furnace tube at a third port for preventing the exhaust gas from leaking. The vacuum seal is connected to the exhaust subsystem at the first node and the second node. Finally, an N.sub.2 sealing tube is connected to furnace tube and surrounding the seam between the furnace tube and the bottom board.

    Abstract: The present invention comprises means for sublimating and handling ammonium chloride (NH.sub.4 Cl) vapor, a bi-product of a silicon nitride growth process, thereby preventing backstreaming into the reactor and ingestion of vapor and particulates by the vacuum pump. The exhaust circuit comprises a novel combination of valves, sublimation and cold traps, cooling and heating elements to facilitate reduction of condensed NH.sub.4 Cl volume from a first path trap thus reducing maintenance, increasing production up-time and enhancing product yield.
