Title: Photomask and method for measuring phase difference
Inventor: HAYANO KATSUYA
IPC: G03F1/68
Filed: 1994-02-08
Abstract: PURPOSE:To find the phase difference of a phase shifting mask simply with a good accuracy, by providing in the regions having no influence on the structures of elements the main and auxiliary patterns for measuring phase differences wherefrom the patterns for constituting the elements are excluded, and by providing a phase shifter in either the main or auxiliary pattern. CONSTITUTION:In the parts of a mask wherefrom the regions for elements are excluded, main patterns 5, 7 and auxiliary patterns 6, 8 wherefrom the patterns for constituting the elements are excluded are provided respectively. Hereupon, phase shifers 3 are so provided respectively in the patterns 6, 7 that the phases of the lights transmitted through the main patterns 5, 7 and the phases of the lights transmitted through the auxiliary patterns 6, 8 are different from each other, and further, the dispositions of the phase shifters 3 are made opposite to each other. After the transcriptions of the patterns, the dimensional difference between the transcribed patterns of the main patterns 5 and the main patterns 7 fitted with the phase shifter 3 is found by the observations through an optical microscope, etc. Also, the relation between the changing quantity of the transcribed dimension of the patter and the phase difference of the mask is calculated at a certain focal distance, and this relation is considered as a calibration curve, and further, by the use of the calibration curve, the phase difference of the mask can be found without any measurement of the film thickness of the phase shifter 3.

IPC: F16L9/18
Filed: 1978-02-10
Abstract: PURPOSE: To transport liquid hydrogen and others with less loss of evaporation by arranging one or more pre-cooling pipes with pre-cooling medium passages in contact with the main pipe among transport pipes in a heat-conductive state.  
     CONSTITUTION: A low-temperature valve 11 is opened to conduct liquid nitrogen of pre-cooling medium from a liquid nitrogen supply port 10 into the first pre-cooling pipe 3 among transport pipes under a reduced pressure, and then another low- temperature valve 13 is opened to discharge the nitrogen into the air from a branch pipe 12 through a discharge port 14. Since a main pipe 1 is in contact with the first pre-cooling pipe 3 in a heat-conductive state, it is gradually reduced in the temperature. When the temperature is reduced almost to 100 degrees K in the centre of the long transport pipe, the low-temperature valve 13 is closed and a bypass valve 15 is opened. Then, a valve 17 is opened to cool the second pre-cooling pipe 7, and nitrogen gas is discharge into the air through an exit 18. Thus, the main pipe is cooled, and the evaporating loss of liquid hydrogen and others in the main pipe can be reduced.
