Patent JP-H09116095-A (JP)
Title: Semiconductor device and its manufacture
Inventor: SHIOKAWA YOSHIMASA
IPC: H01L21/316
Filed: 1995-10-16
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device which has a capacitive element constituted of an insulating film that has only a small surface unevenness and a high dielectric strength and also provide a method for manufacturing it. SOLUTION: On a thermal oxide film 2 formed on an Si substrate 1, a polycrystalline Si layer 3 of 2500Å in thickness is formed as a lower electrode of a capacitive element by the low-pressure CVD method. This substrate 1 is heat-treated with phosphorus oxychloride being used as a source gas to form an extremely thick PSG film 6 on the polycrystalline Si layer 3. By this heat-treatment, a polycrystalline Si layer 3a with grown Si grain boundaries can be obtained. After removing the PSG film 6 by etching with an HF liquid, the substrate 1 with the polycrystalline Si layer 3a is heat-treated in O2 gas at 1135 deg.C for 120 seconds by rapid lamp heating to form an insulating film 5 on the surface of the Si layer 3a.  Since this heat-treatment is conducted for a very short time, the growth of the grain boundaries of Si is prevented and therefore the insulating film 5 of a surface unevenness of 80Å or below is formed by a high-temperature stress relaxation effect. In like manner, a polycrystalline Si layer 4 is formed as an upper electrode on the insulating film 5 and is patterned. After that, part of the lower electrode is exposed and the upper and the lower electrode are wired and thus a capacitive element is fabricated.

IPC: B24C1/10
Filed: 1987-10-23
Abstract: PURPOSE:To improve resistance to scuffing and resistance to wear, by a method wherein, after the inner peripheral surface of a cylinder on which rigid chrome plating is applied is smoothly finished, sand blast processing and further honing processing are applied to form a plateau part having fine pits and a given area ratio. CONSTITUTION:Rigid chrome plating is applied on the inner peripheral surface of a cylinder made of an alumina alloy. After the inner peripheral surface is precisely polished to a specified inner size by internal polishing or honing, no. C-7 silica sand is blasted by means of an air pressure of approximate 2-5 kg/cm<2>, and a satinlike uneven surface having surface roughness of Hmax 3-5mum is formed. Subsequently, by using a grinding stone, e.g. cork, vinyl, honing processing is applied to form a plateau part, having pits with a depth of 1.2-3.5 and an area ratio of 20-50%, on the surface of the rigid chrome plated layer. This method enables provision of a high-quality plated cylinder which has excellent resistance to scuffing and resistance to wear.

Title: Designing method for clock wiring
Inventor: KOYAMA AKIO
IPC: G06F17/50
Filed: 1994-10-31
Abstract: PURPOSE: To obtain a clock wiring layout which is uniform in rise/fall time at a terminal and small in skew. CONSTITUTION: After a tree type clock wiring layout is temporarily designed by a zero schema merging method (step S1), a point where the rise/fall time of a clock is less than a permissible value is found by a terminal circuit on the tree if the rise/fall time of the clock exceeds the permissible value (steps S2-S4), and a buffer amplifier is inserted there (step S5).  Then, wiring layout information on the higher-order than or upstream side from a trf-allowing point is discarded (step S6) and the delay of the tree on the lower-order than or downstream side from the trf-allowing point is considered to design a tree type layout again by the zero schema merging method (step S7), and it is judged whether or not the rise/fall time of the clock at the buffer insertion point exceeds the permissible value and if the permissible value is exceeded, a buffer amplifier is inserted at the trf-allowing point, thus repeating the procedure.

Title: Fluorescent lamp
Inventor: IMAMURA HITOSHI
IPC: H01J61/30
Filed: 1985-11-30
Abstract: PURPOSE:To reduce the size and weight of a fluorescent lamp by forming its discharge control plate from a metal plate coated with a glass, ceramic or similar electrically insulating material. CONSTITUTION:A discharge control plate 13 is formed by coating its surface with a glass, ceramic or similar electrically insulating material. Discharge is started when a discharge starting voltage is applied across a pair of electrodes 12a, 12b, and makes a turn through a dome-shaped space at the top in a glass bulb 10 as a discharge path is bent in an inversed U shape by the regulation of a discharge control plate 13. Although an impurity is emitted from the discharge control plate 13 during the discharge between the electrodes 12a, 12b, its quantity is quite small because the outer surface of the metal plate 13A which stores the impurity gas is coated with a thin glass film 13B to prevent the impurity gas emission. Consequently, deterioration of the electric characteristic due to the emission of the impurity gas can be remarkably mitigated.
