Title: Apparatus for etching silicon
Inventor: KADOMURA SHINGO
IPC: H01L21/3065
Filed: 1987-09-28
Abstract: PURPOSE:To make it possible to form an etching groove or a hole having a high aspect ratio and no surface roughness, by coating at least one of counter electrodes with an organic material. CONSTITUTION:In a silicon etching apparatus in which a silicon is etched with an etching gas comprising at least silicon chloride and nitrogen by applying a voltage to counter electrodes 2 and 3, at least one of the counter electrodes is coated with an organic material. For example, the organic material is coated on both of the counter electrodes 2 and 3 or at least cathode electrode 3. In this case, a quartz layer 12 made of heat resistant quartz is coated on a metal electrode plate 11 and then an organic material 13 of polycarbonate and the like is coated thereon. As a result, since carbon and hydrogen are introduced from the organic material coated on the electrode surface and carbon or carbonic polymer is attached on the inner wall of the etched groove or hole, the silicon surface is protected and the inner surface can be prevented from being roughened.

Title: Luminance signal and color signal of television signal processing system
Inventor: HIRANO YASUHIRO
IPC: H04N9/78
Filed: 1984-11-21
Abstract: PURPOSE:To perform the separation of Y (luminance signal) and C (color signal) for both a still image and moving image without deterioration in picture quality by multiplexing Y-C split mode information, which was found from luminance signal spectrum, with a television signal at sending side, and by performing the Y-C split based on this mode information at receiving side. CONSTITUTION:The spectrum of the luminance signal Y is found at the sending side by a time space filter. Using the cascade connection of a time direction filter 3, vertical direction filter 4 and horizontal direction filter 5 (high-pass filter 1), and an output signal obtained from a horizontal filter 6 (high-pass filter 2), a mode discriminant circuit 7 determines the Y-C split mode of the receiving side. If the discriminant mode is interfield Y-C, a switch 1 selects the signal, from which the luminance signal component superimposing the color signal component is removed, by the time space filter 2. In addition, an adder 10 multiplexes it with Y-C split mode information. With the mode information multiplexed with the television signal, the receiving side determines the Y-C split mode information in a mode control circuit 11, and selects the signal corresponding the mode in a switch 12.
