Filed: 1985-10-07
Abstract: PURPOSE:To improve the effective sensitivity of a resist and to execute satisfactory lithography by incorporating a fluorescent material which generates fluorescent rays by receiving the irradiation of energy into a photosensitive material. CONSTITUTION:The fluorescent material 7 which generates the fluorescent rays to sensitize the photosensitive material for execution of lithography by irradiating the irradiation energy generated form, for example, an X-ray source 1, etc., via a mask pattern 3 and projecting the pattern is incorporated into said photosensitive material. The photosensitive material i.e., the resist 6 is sensitized by both of the secondary irradiation rays from such fluorescent material 7 and the irradiation energy and therefore, the effective sensitivity of the resist is improved and the satisfactory lithography is made executable. The lithography is executable by the relieving strict conditions for X-ray transmittivity, thickness, etc. as a thin film 4 for holding the mask material. Since only the sensitivity is increased while the performances of the respective resists are maintained, this lithographic method is extremely advantageous.

IPC: H04N5/21
Filed: 1986-09-18
Abstract: PURPOSE:To improve S/N and to reduce the fault of an after image by outputting a signal as it is when a new video signal component is large, and outputting the signal after adding an original signal component when it is large. CONSTITUTION:A comparator 7 compared the digital signals (a) of new video signals with the digital signals (b) of original video signals. When the level of new video signal is larger, an addition control circuit 8 is controlled to record the digital signals (a) of new video signals again in a memory 4 as they are, and when the level of original video signals is larger, the circuit 8 is controlled to add by 1/2 of (a) and (b) and record again in the memory 4. Thereby, real image information is outputted without generating the after image. When photo did not enter the part, the after image is generated as added to former level 1/2 by 1/2. However, since it acts so as to keep and display real image information, the improved effect of S/N suppressing the increase of the after image can be obtained.
