Abstract:
A substrate processing system comprising:a housing defining a preheater for preheating a substrate, a buffer region operably connected to said preheater, and a process chamber operably connected to said buffer region;a substrate holder, located within said process chamber, for holding said substrate;a substrate moving system within said buffer region for moving said substrate from said preheater, through said buffer region and into said process chamber;at least one temperature control system for maintaining a first selected temperature within said preheater and a second selected temperature within said process chamber;at least one pressure control system for maintaining a first selected pressure within said preheater, a second selected pressure within said buffer region, and a third selected pressure within said process chamber;a controller for controlling said substrate moving system, said temperature control system and said pressure control system; anda memory coupled to said controllers said memory comprising a computer-readable medium having a computer-readable program embodied therein for directing operation of said substrate processing system, said computer-readable program comprising;instructions for controlling said preheater and said temperature control system to preheat a substrate in said preheater to a desired substrate temperature;instructions to control said substrate moving system to move said substrate from said preheater through said buffer region and into said process chamber; andinstructions for controlling said pressure control system to maintain a pressure within said buffer region between about two (2) Torr and about seven hundred and sixty (760) Torr.
