Title: Photomask for printing circuit and exposure method using this
Inventor: YOSHINO TSUNEO
IPC: G03F1/60
Filed: 1981-04-22
Abstract: PURPOSE:To enable a large area of photomask to be brought into uniform close contact with a photoreceptor for printing a circuit by evacuation, by using the photomask for circuit printing having through holes in the light-transmitting parts of a circuit printing pattern. CONSTITUTION:A photomask 3 for printing a circuit having through holes 6 in the light-transmitting parts 8 of a circuit printing pattern is overlaid on a photosensitive film 2 for circuit printing, further, a film 7 having fine roughness is overlaid on the face in contact with the photomask 3, and then, it is exposed to light emitted from a sheet-like light source. Since the use of the sheet-like light source does not form the pattern of the holes 6 of the photomask 3 on the photosensitive film, and the holes 6 and the gaps of the fine roughness allow the air to pass, even a large area of photomask can be easily brought into uniform and secure vacuum contact with the photosensitive film for printing a circuit to expose it.

IPC: B41M5/36
Filed: 1995-02-24
Abstract: PURPOSE: To obtain an image erasing method capable of rapidly erasing a recorded character or image and a recording medium therefor.
