Title: Exposing apparatus
Inventor: TAKAHASHI KAZUO
IPC: H01L21/67
Filed: 1985-04-30
Abstract: PURPOSE:To improve the alignment precision in addition to the features of global alignment process with high throughput by a method wherein shot position corrected values are measured in terms of the deviation from the printed target position per short of each wafer. CONSTITUTION:A wafer is set up on the first shot position of a wafer chuck and then deflection Cm from the target position is measured as a corrected value Qm, 1 in case of alignment. The second wafer is processed likewise but the mean value Qm, 2 between the corrected value Qm stored in a memory and the second deflection Cm is measured as new corrected value to be stored. Besides, the different (DELTAQm) between the corrected values Qm, 1 and Qm, 2 is also measured. Later the wafers are printed and if the trends of position deviation of patterns printed in the preceding process show resemblances among one another, the fluctuation DELTAQm in corrected values begins to be reduced at the print when several wafers are processed. Moreover when the DELTAQms are checked and detected to be less than specified tolerance T2, the dispersion of position deviations between the target position and the aligned positions can be judged as small.

Inventor: TANIGUCHI YOSHIAKI
IPC: G01L1/00
Filed: 1989-04-11
Abstract: PURPOSE:To visualize a low sound pressure ultrasonic wave by mounting an image intensifier on an image pickup device. CONSTITUTION:When a glass sample 5 is irradiated with laser beam pulses 9, the glass surface reaches high temperature to cause thermal strain, which is propagated as an elastic wave into the glass. Then the irradiation timing of the laser beam 9 is detected by a photodetector 10 and a light source 1 is turned on with a delay time so as to capture the elastic wave as a still image. The elastic wave, however, is extremely low in sound pressure and extremely weak light, so the elastic wave can not be captured as an image by the image pickup device 7 itself. For the purpose, the image intensifier 11 which is a photoelectron amplifier is mounted on the image pickup device 7 to form the image. Namely, the elastic wave of low sound pressure which is propagated in the glass sample 5 is amplified by the image intensifier 11 and can be visualized by the image pickup device 7.
