Title: Aligner and fabrication of device
Inventor: TAKAHASHI KAZUHIRO
IPC: G03F7/20
Filed: 1996-10-11
Abstract: PROBLEM TO BE SOLVED: To expose a substrate with a correct amount of exposure by providing means for sustaining the transmittance of an illumination optical system at a substantially constant value. SOLUTION: An illuminance meter 11 is shifted into the illumination area of a projection optical system 8 by means of an XY stage 9. Light is then emitted from a laser 1 and the transmittance is measured for optical systems 7, 8 based on the ratio of output between a detector 10 and the illuminance meter 11. When the transmittance thus measured exceeds over a predtermined range, light is emitted from a light source 1 by delivering a command from a main control section 13. The ratio of output between the detector 10 and the illuminance meter 11 is also measured during emission of light in order to determine the transmittance of the optical systems 7, 8 and when it reaches a target value within a specified range, emission of light from the laser 1 is interrupted by the main control section 13. The aligner measures the quantity of light being accumulated during exposure using a beam splitter 5 and the detector 10 and controls exposure of a photosensitive substrate W. According to the method, the photosensitive substrate can be exposed at a correct intensity by sustaining the transmittance of the optical systems 7, 8 at a substantially constant value.

Inventor: MITSUOKA YOSHIAKI
IPC: B28B1/52
Filed: 1988-10-26
Abstract: PURPOSE:To make washing of dehydrated felt unnecessary by holding stably filtering resistance of the dehydrated felt, by a method wherein a green plate body is molded of the dehydrated felt comprised of cloth with a monofilament made of synthetic resin, which is dried, cured and an inorganic plate is formed. CONSTITUTION:An inorganic powdery slurry 1 is fed within paper making box 2 and a green plate body 5 is molded while filtering the inorganic powdery slurry 1 with a dehydrated felt 4 comprised of cloth with a turnable monofilament made of synthetic resin of a long net type paper making machine 3. After cutting the same into standard lengths, patterning is performed, cured by drying with a drier and an inorganic plate 8 is formed. It is appropriate that permeability of the dehydrated felt 4 is 50-200cc/sec, which is selected in accordance with a paper making rate. An inorganic powdery body is in a tendency where the inorganic powdery body is clogged especially when the permeability of the dehydrated felt is less than 50cc/sec and when the permeability exceeds 200cc/sec, water filtering properties become too good and molding becomes impossible. Since the inorganic powdery body in a pulverized powder does not stay on the dehydrated felt 4, also washing of the dehydrated felt 4 with washing or acid is not required, therefore, one process can be omitted.
