Filed: 1984-04-02
Abstract: PURPOSE:To obtain a reproducing picture with high quality by increasing the electron beam spot diameter in comparison with a normal case in reproducing white longitudinal lines so as to prevent the reproduced white longitudinal lines from being colored. CONSTITUTION:A luminance signal fed to an input terminal 10 is formed into a high frequency signal via an HPF11 and fed to a voltage comparator 12. In reproducing minute white longitudinal lines, since the signal frequency component is higher than the cut-off frequency of the HPF11, the luminance signal passes through the HPF11 without being modified and a portion exceeding a prescribed voltage (EREF-VD) is extracted by a voltage comparator 12. Moreover, a luminance signal fed to the terminal 10 is fed also to a 2nd order differentiation circuit 14, a large voltage change in the horizontal direction such as minute white longitudinal line is detected by a detection circuit 5, and fed to a voltage amplifier 17 together with an output of the voltage comparator 12. Thus, the control voltage of the white longitudinal line goes to a high level and the focused voltage of the horizontal profile is increased, allowing to increase the diameter of electron beam spot.

IPC: H01L27/108
Filed: 1996-02-26
Abstract: PROBLEM TO BE SOLVED: To prevent generation of insulating film breakdown of a capacitance film and enable prevention of increase in thickness of an interlayer insulating film, by forming a contact hole connecting source and drain regions to a lower electrode, then removing a planarized film, and forming the lower electrode directly above an etching stopper. SOLUTION: A MOS transistor is formed on a semiconductor substrate 1. A first interlayer insulating film 6 is formed and a wiring silicide 7 is formed thereon. Then, an etching stopper film 12 is formed and a planarized film 13 is formed. A contact for connecting N-type source and drain regions 5 to a lower electrode 8 is formed. After that, only the planarized film 13 is selectively removed, thus forming the lower electrode 8 of cylindrical shape. Since the planarized film 13 exists on the etching stopper 12 until formation of the capacitance contact, thickness loss of the etching stopper 12 due to the etching damage may be reduced, and an etching solution may be prevented from passing through the etching stopper 12. Also, generation of insulation breakdown of the capacitance film due to thermal stress or the like may be prevented.
