Title: Mask and method for exposure using the same
Inventor: KAWASHIMA MIYOKO
IPC: G03F1/70
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To obtain a pattern image of high resolution having const. contrast of a periodical pattern without depending on the pitch and having a decreased error of the pattern line width by using a mask to transfer the pattern on a photosensitive substrate by multiple exposure and using the mask having a plurality of periodical patterns having different pitches and the same pattern line width. SOLUTION: The periodical pattern of the mask includes a plurality of periodical patterns having the same pattern line width L and different pitches, and the interval S of the pattern is varied for regions according to the pitches. The center position of the periodical pattern is controlled to coincide with the image forming position by normal pattern exposure. The pitch P is defined by P=L+S. When the pattern interval S is decreased, the pitch P becomes equal to the pattern line width L. The distance D12 on the border is properly determined according to the line width L so that the center position of the periodical pattern is coincident with the image forming position by normal pattern exposure.

IPC: G01M3/04
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To be easily laid and to detect leakage of inorganic salt or the like leaking water in an overall area. SOLUTION: A surface of the water barrier sheet having predetermined thickness and area is partitioned to a plurality of unit areas 11. A transponder 20 for transmitting a predetermined response signal and an ion concentration sensor 30 connected to the transponder 20 when a predetermined question signal is received at each area are arranged underneath a lower surface of the sheet, and a detection result of an ion concentration is contained in the signal.
