Title: Photomask plotting device
Inventor: WAKIMOTO YOSHIKO
IPC: G03F1/68
Filed: 1989-12-14
Abstract: PURPOSE:To reduce the number of working man-hour by automatically feeding a film where plotting is performed to a developing part. CONSTITUTION:The unexposed film 2 is attracted to a plotting table 1 and scanned with a laser beam while moving the table 1. A photomask pattern is plotted by a plotting part 3 and the film 2 where the plotting is performed is fed to the developing part 6 by a handling part 4 so as to blacken only a part which is irradiated with the laser beam. Then, the film 2 is allowed to pass through a feeding guide 11a by a reverse roller 12 to be fed to a fixing part 7. After removing unexposed emulsion, the film 2 is allowed to pass through a guide 11c by the roller 12 to be fed to a drying part 9. After being dried, the film 2 is fed to a film output part 10 by the roller 12 and then plotting and developing are finished. Thus, plotting and developing stages are consecutively completed by one device and the number of working man-hour is drastically reduced.
