Inventor: NARA KEI
IPC: G03F7/20
Filed: 1997-11-12
Abstract: PROBLEM TO BE SOLVED: To enable double exposure of a region where the unequal application of a photosensitive agent occurs without the use of a special device by subjecting the position where the unequal application of the photosensitive agent occurs before or after the exposure for pattern transfer by a first illumination system to the partial exposure by a second illumination system. SOLUTION: The objection regions 13A to 13E by the first illumination system are so arranged that the regions adjacent to each other in a Y direction are displaced to a prescribed amt. with each other in an X direction and that the ends of the adjacent regions overlap on each other in the Y direction as shown by broken lines. The spot exposure regions SA1 to SA3 by the second illumination system are arranged to be adjacent to each other in the moving direction of a carriage with respect to the exposure range EA by the first illumination light. Then, the band-shaped region PR1 on a substrate PG is double exposed by the projection region 13A and the spot exposure region SA1 simultaneously at the time of transferring the pattern regions onto the substrate PG.  Similarly the band-shaped region CB is double exposed with the projection region 13C and the band-shaped region PR2 with the projection region 13E respectively by SA2, SA3.

Abstract: PURPOSE:To simplify the working for fixing many probes on an insulating base member and to make it possible to perform stable measurement highly accurately in a high temperature environment wherein the temperature is changed by providing the probes in grooves in a ceramic base table, and fixing the probes. CONSTITUTION:Grooves 12 are formed in a hollow, disk-shaped ceramic base table 10 in conformity with the electrode pitch of a body to be checked 1. Probes 20 are provided in the grooves 12. The probes are fixed with insulating resin 40. Therefore, insulation between the probes 20 on the base table 10 is secured with the ceramic material that is present between the grooves 12. Furthermore, the ceramic material is stable and is not contracted by the temperature of an atmosphere and the change in temperature environment. The insulation resistance of the base table 10 supporting the probes 20 at normal temperature is high. The insulation between the probes 20 is not decreased because of the characteristics of the ceramics even if the temperature is increased. The insulation is rather improved by drying. Therefore, excellent insulating characteritics can be secured from normal temperature to high temperature all the time.
