Abstract:
A system for loading, processing and unloading substrates, comprising:a carrier having a bottom and a plurality of slots to receive a plurality of substrates for processing in a reactor, wherein the reactor is tubular and has an inlet opening to receive said carrier loaded with said substrates; a handling robot configured to load and unload said substrates to and from said carrier when said carrier is located outside said reactor; a rotatable base plate configured to support said carrier and to move said carrier between a first position in proximity of said handling robot and a second position in proximity of said reactor; a lifting device configured to introduce and remove said carrier in and from said reactor by lifting and lowering said carrier from and to the base plate when the carrier is in said second position; a door plate configured to be coupled to said lifting device and to said bottom of said carrier, said door plate further configured to close the inlet opening of said reactor when said carrier is introduced in said reactor and to seal said reactor during processing; a coupling mechanism configured to act upon said bottom of said carrier and through said door plate to thereby rotate said carrier when said carrier is introduced in said reactor so that said substrates are uniformly processed; and a drive motor stationarily arranged and configured to activate said coupling mechanism to rotate said carrier when said carrier is introduced in said reactor.
