Title: Manufacture of integrated circuit, and projection aligner
Inventor: SUZUKI KAZUAKI
IPC: G02B19/00
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To keep accurately the imaging characteristic of a projection lens even when the distribution state of its incident light is varied, by adjusting a projection optical system corresponding to a luminous flux for irradiating uniformly a mask, to the size or shape of a light source to be formed on the outgoing side of an optical integrator. SOLUTION: With regard to light fed from an illumination light source 10, a parallel light flux obtained via a shutter 12, etc., is projected on an optical integrator 16, and further, the light is bent downward passing an aperture diaphragm 18 to pass the light through a projection lens 24 after its transmission of a mask R and project it on a wafer W. In the aperture diaphragm 18, to its preset numerical aperture, by a selector 40, its pertinent time constant is selected from a memory 42. Inputting this time constant to a main controller 28, the fluctuation quantity of the multiplying factor of the lens 24 is determined. By both the fluctuation quantity and the sensed value of a pressure sensor 38, driving a pressure regulator 32, the pressure in a sealed lens chamber 24 is controlled.  Thereby, regulating the multiplying factor of the projection lens 24 to a predetermined value, the imaging characteristic of the projection lens 24 is maintained accurately by correcting the optical characteristic of the projection lens 24 itself.

Abstract: PURPOSE:To always monitor an abnormal state by detecting current flowing through a change-over switch, with an optical CT, to conduct the current with an optical cable for photoelectric conversion, at the time of the tap change-over of a transformer under working, and by finding a change-over time and the scale of the flowing current. CONSTITUTION:The tap of a voltage change-over switch 2 in an oil tank 1 its selected by a selector 3, and the output voltage of a transformer under working is regulated. In its case, under change-over operation, current flowing to a conductor 4 for connecting the change-over switch 2 and the tap of the selector 3 to each other is detected by an optical CT 12 fitted in insulation oil, and is transmitted to an optical cable 13, and the input to a photoelectric converter 14 outside the oil tank is provided. The input of electric signal from the photoelectric converter 14, to a monitor 14a is provided, and the scale of current and a tap change-over time are measured, and the existence of an abnormal state is discriminated. If the abnormal state exists, alarm is generated and operation is stopped. As a result, a working state is always monitored, and the abnormal state is found earlier, and the damage of an equipment due to the abnormal state is limited to a minimum.

IPC: B41J2/165
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To provide an ink jet recording head capable of preventing crosstalk from occurring and supplying a sealing liquid quickly. SOLUTION: An ink ejection nozzle 12 is provided in a head 10 and the ink ejection nozzle 12 is sealed with a sealing liquid 22 so as to prevent drying of the nozzle 12.
