Title: Projection aligner and aligning method
Inventor: HORIUCHI TOSHIYUKI
IPC: G03F7/20
Filed: 1993-08-30
Abstract: PURPOSE:To provide a projection aligner in which the positional uniformity of exposure intensity is enhanced by suppressing the fluctuation of illuminance on a substrate to be exposed positively not by try and error but fixedly with no individual difference. CONSTITUTION:A translucent liquid crystal matrix plate 1 is interposed between a second illumination optical system 14 and an original pattern substrate 15. A brightness controller 2 for liquid crystal conducts a operation for determining the 'bright' and 'dark' of each liquid crystal cell on the matrix plate 1 according to the fluctuation in the illuminance on a substrate 18 to be exposed and delivers a command. Each liquid crystal cell can take only one of 'bright' or 'dark' state but each point on the original pattern substrate 15 is subjected to overlapped illumination by the lights transmitting many liquid crystal cells of the matrix plate 1 and the 'dark' cells project shades continuously over a wide range on the substrate 15. Consequently, when 'dark' and 'bright' cells are set appropriately, the illuminance distribution can be improved arbitrarily according to the fluctuation of illuminance on the original pattern substrate 18.

IPC: G03B27/46
Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To improve the processing efficiency by eliminating the futile time in the processing as much as possible. SOLUTION: As soon as photographic paper 16 is fed from a temporary housing part 34 to an exposure stage 78, the next photographic paper 16 is carried to the housing part 34. When the final photographic paper 16 is transferred to the housing part 34, a ball screw mechanism part 38 is actuated and the photographic paper is carried and controlled in the same manner as the above by making a pair of rollers 28 correspond to an adjacent carrying path. By replacing a magazine which is empty with a new one in the midst of processing by using either magazine, the magazine is replaced without temporarily stopping the processing, so that working efficiency is improved. The replacing feasible time is kept until the photographic paper 16 in either magazine is used up.  Since an operator need not always perform monitoring and has only to periodically perform monitoring at comparatively long intervals, workability in maintenance is improved.
