IPC: B65G47/88
Filed: 1988-02-09
Abstract: PURPOSE:To enable a high-speed and high-efficiency process and shorten a tact time by providing a plurality of work positions in a carriage route and a standby position between the aforesaid work positions. CONSTITUTION:A workpiece placement table 5 loaded with a workpiece after a process at the first work position 6 is sent to a standby position 30 and then up to the position of a gate 31. Then, a sensor 34 operates to detect that the workpiece is already processed. On the basis of the detected signal, a gate 31 is opened, thereby sending the table 5 to an unloader unit 3 via the second work position 7. It follows, therefore, that the first work position 6 and the second work position 7 do not interfere with each other in a single conveyor 1 and the predetermined process of the workpiece can be carried out smoothly. As a result, it is possible to do a high-speed and high-efficiency work at each process and to reduce an overall tact time.

Abstract: PROBLEM TO BE SOLVED: To minimize a dead time due to proximity effect correction calculation and improve the writing precision in the peripheral portion of a pattern, by carrying out proximity effect correction calculation during preliminary exposure at least with a minimum correction luminous exposure, and correction lithography for insufficient preliminary luminous exposure and actual proximity effect correction, thus performing exposure twice in total. SOLUTION: The writing coordinate, shot dimension, and standard luminous exposure outputted from a shot dissolving circuit ultimately drive a positioning deflection control circuit, a shaping deflection control circuit, and an irradiation time control circuit, respectively. An area density calculation circuit calculates the exposure area density corresponding to the writing coordinate from a shot dimension area and additionally writes it to a map memory circuit.  In this case, lithography processing for area density correction calculation is carried out while preliminary exposure is carried out once for a constant irradiation time T1 with a minimum value of correction luminous exposure or less, and correction lithography is carried out again for an irradiation time T2 in accordance with the calculated area density distribution, thus carrying out lithography so that the sum of the variable irradiation time T2 and the previous constant irradiation time T1 is equal to an appropriate luminous exposure of corrected proximity effect.
