Abstract: PURPOSE:To realize the mass production of an optical circuit and a small loss by forming a hollow glass tube or a columnar glass bar, which has a high- refractive index core layer and a low-refractive index clad layer, into a plane plate with wire drawing while rolling or stretching it. CONSTITUTION:A glass layer 6 which should become a core is formed on the surface of the inside wall of a hollow glass tube 5 by CVD, and a refractive index controlling dopant such as P, Ge, or the like is added to the glass film 6 to give a desired refractive index or refractive index distribution. This hollow glass tube is subjected to wire drawing while rolling or stretching it to obtain a plane plate-shaped optical waveguide. The glass film 6 and the hollow glass tube 5 become a core layer and a clad layer 7 of the optical waveguide respectively. Thus, the mass production and a small loss of the optical waveguide are realized.

Title: Semiconductor integrated circuit device
Inventor: KURODA KENICHI
IPC: G11C16/06
Filed: 1984-04-06
Abstract: PURPOSE:To improve read/write characteristics of an EPROM by impressing a grounding potential and a substrate backup bias voltage in accordance with selection and non-selection of a floating gate/avalache injection MOSFET(FAMOS) of an element forming area. CONSTITUTION:When FAMOSQ11-Q1n of an element forming area of a memory array M-ARY are selected through, for instance, a word line WL1, etc., an FETQ2 of a switch circuit S1 is turned on, and a substrate back bias voltage is supplied to the element forming area from a substrate back bias voltage generator circuit VBB-G. Conversely, when they are not selected, an FETQ1 is turned on, and a grounding voltage is supplied, whereby relative threshold voltages of the FAMOSQ11-Q1n change in accordance with the selection and non-selection. Consequently, a conductance characteristic of the FAMOS where writing is carried out at the time of writing becomes larger, and most parts of a write current blow, which causes a leak current to the non-selected FAMOS to be reduced. This can apply reading, and write/read characteristics of an EPROM can be improved.

Title: Cvd device
IPC: H01L21/31
Filed: 1992-03-26
Abstract: PURPOSE:To enhance operation efficiency without reducing the yield of substrates on which film formation is carried out. CONSTITUTION:When thin films are formed on substrates B, the gas in a film formation chamber 1 is exhausted from the exhaust port 2 by a vacuum pump. Counter electrodes 11 are moved in the directions of the openings 12 in the electrodes 11 with driving devices 15 and the openings 12 are brought into close contact with trays 4a holding the substrates B. A reactive gas is introduced into the electrodes 11 through flowmeters 9 fitted to introduction pipes 8 to keep 50-100 Pa pressure of the gas in the electrodes 11. Plasma is then generated by impressing high-frequency, e.g. 13.56MHz on the electrodes 11 and the reactive gas in the electrodes 11 is brought into a chemical reaction such as decomposition by the plasma to form thin films on the substrates B fitted to the trays 4a. The generation of particles due to the exfoliation of a thin film from the side wall of the film formation chamber 1 is suppressed and yield is enhanced.
