Title: Manufacture of magnetic bubble memory element
Inventor: SAITO GIICHI
IPC: G11C19/08
Filed: 1986-11-06
Abstract: PURPOSE:To prevent the production of hard bubbles at the electrode forming part by implanting ions again to an exposed magnetic thin film in opening a window to an insulation layer. CONSTITUTION:The window 28 is opened by the dry etching method to a 1st insulation layer 13 at least covering a magnetic thin film 12 to form the electrode 26 so as to expose the magnetic thin film 12, and ions of H or Ne are injected to the exposed magnetic thin film 12 to form the ion implantation part 30 to the electrode forming part of the magnetic thin film 12. In forming the pattern made of the permalloy at a 2nd mask level, a permalloy film 24 is formed also on the ion implantation part 30, a resist pattern 29 is formed onto the permalloy film 24 and the electrode 26 is formed by the ion etching method. After the window is opened to the insulation layer, the ion implantation part shaped by the surface of the magnetic thin film is repaired by implanting ions of H or Ne to the exposed magnetic thin film thereby suppressing hard bubbles at the electrode forming part.

Title: Angular velocity detecting device and its driving method
Inventor: NAKAJIMA AKIO
IPC: G01C19/56
Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To improve detection precision by separately providing driving electrodes for a branch for driving and detection electrodes for a branch for detection and suppressing the off-plane vibrations of an oscillator at the time of non-rotation. SOLUTION: The pair of the driving electrodes 11 and 14 of the branch 7 for driving of an oscillator 1, the pair of the driving electrodes 9 and 10, and the pair of the driving electrodes 11 and 14 are connected to an output terminal 79, an output terminal 80, and an output terminal 81, respectively, by connecting lines arranged outside an extension line at the lower part of the branch 7 for driving. In addition, the pair of detecting electrodes 16 and 17 of a branch 8 for detection and the pair of the electrodes 15 and 18 are connected to an output 78 and an output 77, respectively, by connecting lines arranged outside an extension line at the lower part of the branch 8 for detection.  By providing a structure in which the branch for driving and the branch for detection are isolated in this way, the connecting lines of driving electrodes are considerably separated from the connecting lines of the detecting electrodes. Therefore, an electric field due to driving current passing through the connecting lines of the driving electrodes practically exert no effect. In addition, a control circuit 6 suppresses the detection voltage of a detecting circuit 3 due to micro leakage output voltage between the pair of detecting electrodes of the branch 8 for detection to make the occurrence of the micro leakage output voltage zero.

Abstract: PURPOSE: To fill an element separation trench with an insulation film of a uniform quality and to flatten the surface of a semiconductor substrate by forming the trench on the semiconductor substrate, and a flat oxide film on the bottom plane of the trench, and by selectively growing the insulation film in the trench by liquid phase growing. CONSTITUTION: Trenches 2A and 2B are formed in the element isolation area on the surface of a silicon substrate 1. Then, a silicon oxide film 3 is formed on the whole plane including the trench surface by thermal oxidation. A photoresist film 4A is formed on the whole plane, and the trenches 2A and 2B are buried. At that time, the surface of the photoresist film 4A becomes flat. Then, the photoresist film 4B is left only on the bottom plane of the trench by etching. Flat oxide silicon films 3 are left only on the bottom plane of the trenches 2A and 2B by etching. After removing the photoresist film 4B, the trenches 2A and 2B are filled by growing an LP-SiO2 film 5. Thus, the surface of the LP-SiO2 film 5 is also flattened.
