Abstract: PURPOSE:To prevent a through-hole from being broken down and simply form even a landless through-hole by preventing an electro-deposition film in the through-hole from being exposed to light even if a film is displaced upon UV exposure by filling the through-hole with an ink material prior to the formation of the electro-deposition film. CONSTITUTION:A through-hole is formed through a glass epoxy double-side copper laid laminate sheet 2, and a copper plated layer 3 is formed over the entire surface of the laminate sheet 1 including a hole wall. Then, the through-hole 2 is filled with a filling ink material by screen printing, and dried. After a positive type electro-deposition film 5 is formed, a non-used electro-deposition solution is removed and the electro- deposition film 5 is cured by a hot-air drier. Successively, positive type pattern films 6a, 6b are brought into close contact with the electro-deposition layer 5 in vacuum and exposed to light by a UV exposure device, and thereafter dipped in soda metasilicate to melt and remove the exposed portion. Thereafter, unnecessary copper plated layer and a base copper foil are melted and removed, and further the thermosetting epoxy ink 4 in the through-hole 2 and the electro-deposition film 5 are separated and removed to form a through-hole printed wiring board. Upon the exposure, since the electro-deposition film in the through-hole 2 is not exposed to light, the through- hole is prevented from being broken out.

Abstract: PURPOSE:To enlarge the surface area of a lower electrode, by forming an aperture window whose width belongs to an unsaturated region in microloading characteristics, in a conducting layer mask region in a pattern for working the conducting layer as the lower electrode, before the conducting layer is etched. CONSTITUTION:A pattern 10 has mask parts 11 for working the lower electrode of a capacitor of a conducting layer 9, and is formed so as to correspond with each of the memory cell on a wafer.

The conducting layer 9 is etched by an RIE method using the pattern 10 as a mask, and a lower electrode 14 is worked. Since the etching rate of the aperture windows 12, 13 is small, the etching is not ended when the working of the lower electrode 14 is finished, and recessed parts 15, 16 whose depth is (b) are formed in the upper surface of the lower electrode 14. Hence the surface of the lower electrode 14 turns to an uneven form, and the surface area of the electrode is increased.

Abstract: PURPOSE:To allow reproduction with high image quality even in reproduction of recording media which vary in the carrier frequencies of FM signals by discriminating the FM carrier frequency from the reproduced FM signal from the recording medium and automatically switching the resonance frequency characteristics of a head resonance circuit so as to be optimized. CONSTITUTION:The reproduced FM signal transmitted from the recording medium 7 to a head amplifier 3 via a magnetic head 1 is inputted to a VHS/ S-VHS discriminating circuit 6.

The FM signal is automatically so selected as to close the switch S1 at the time of reproducing the recording medium 7 of VHS specifications and to open the switch S1 at the time of reproducing the recording medium 7 of S-VHS specifications and, therefore, the C/N of the reproduced FM signal is improved. The output from the head amplifier 3 is so corrected as to be made into the signal optimum for FM demodulation by processing this output in an FM AGC equalizer 4 and is thereafter demodulated to a reproduced video signal by an FM demodulator 5. The repro duced video signal good for both VHS and S-VHS is, therefore, obtd.
