IPC: H04N9/86
Filed: 1980-04-23
Abstract: PURPOSE:To make a special reproduction easy by arraying color signals so that color difference signals stand in a line completely between the tracks, in case of recording a television signal of the reset line sequentialy system. CONSTITUTION:The tracks 22, 23 record a color difference signal by 1H-delaying, and those of 21 and 24 are not delayed. According to such a constitution, the color difference signals also stand in a line completely with the adjacent track, therefore, it becomes easy to execute various kinds of special reproduction. When reproducing, it can be executed by 1H-delaying a color difference signal of the track which has not been 1H-delayed at the time of recording. In this way, as for the color difference signal, since all the tracks are 1H-delayed against a luminance signal, it is necessary to 1H-delay the luminance signal, as well, at the time of reproduction in order to match the timing.

Abstract: PURPOSE:To eliminate measurement errors caused by drifting and the like and improve the alignment accuracy by a method wherein a mark on a wafer side is composed of a plurality of linear patterns arranged symmetrically against an axis and the left and right images of the linear patterns arranged symmetrically against an axis are independently observed. CONSTITUTION:A plurality of linear patterns 21a-21c are formed in a wafer mark 21 symmetrically with respect to an axis A. The linear patterns 21b and 21c are individually observed and a point where the respective luminous powers coincide with each other is obtained as an aligning point by a suitable signal processing circuit. After the reflected image of the wafer mark 21 passes through a reticle mark 11, the reflected image is measured by one photoelectric sensor 38 in a time-sharing manner. For that purpose, the whole image is vibrated by the vibration of a mirror 35. By obtaining the difference between the respective detection signals of the photoelectric sensor 38 when the image of the pattern 21b is detected and when the image of the pattern 21c is detected, the relative discrepancy between the marks 11 and 21 is measured. Therefore, the alignment of the reticle mark 11 and the wafer mark 21, i.e. the alignment of a mask and a wafer can be performed in accordance with the discrepancy.
