Technical field
The utility model relates to a kind of synchronous transmission device of linear pattern production equipment, relates more specifically to a kind of straight-line transmitting communication system that is applied to the synchronous transmission device of linear pattern oganic light-emitting display device and linear pattern thin film solar production equipment and has this device.
Background technology
In the semiconductor machining industry, cluster type (cluster) production system is adopted in the manufacturing of undersized semiconductor device such as integrated circuit usually, shown in accompanying drawing one, utilize a plurality of conveying chambers 502 to be polygonal shape with circumferentially flexible manipulator, and around conveying chamber 502, being provided with a plurality of process chambers, its film formation process unit has: to the conveying chamber 504 of chambers conveying substrate; Substrate is sent into the substrate of conveying chamber and sent into mouth; The purge chamber 505 of cleaning base plate; The encapsulation chamber 506 in a plurality of film forming room 503 of film forming and later stage, hothouse 507, finished product conveying chamber 508 etc. on substrate, these process chambers by a plurality of gate valves be configured in conveying chamber around etc. structure.
Because the extraction vacuum time for a long time, is frequently opened cavity and is made the effusion of film material between unsuitable excessive, each chamber of this equipment cavity body structure, cause it to have problems such as incompatibility large-area substrates film forming, the Coating Materials utilance is low, the production cycle is long, so linear pattern (inline) semiconductor manufacturing facility just has been suggested.Linear semiconductor production equipment, have the film forming room that can independently control vacuum degree and linearly be arranged in the same vacuum tank a plurality of, and do not need gate valve between these film forming room, manage the chamber throughout, under different conditions, can carry out and reach the predetermined process of purpose separately.During film forming, substrate forms film simultaneously by conveying device continuous conveying above a plurality of film forming room of continuous conveying substrate, shortens time that vacuum degree was carried and adjusted to substrate with this, and then shortens the production time.
