Title: Manufacture of semiconductor device
Inventor: MURAKAMI KENJI
IPC: H01L21/316
Filed: 1986-11-18
Abstract: PURPOSE:To prevent the generation of the lowering in the breakdown strength of a gate oxide film, and to improve yield on manufacture and reliability by leaving a polycrystalline silicon film having a selective etching rate with a second insulating film in the foundation of the oxidation-resistant second insulat ing film used when a field oxide film is formed onto a semiconductor substrate. CONSTITUTION:A first insulating film 11, a polycrystalline silicon film 12 and an oxidation-resistant second insulating film 13 are deposited onto the surface of a semiconductor substrate 10, and the second insulating film 13 is etched selectively to shape a mask for oxidation. A field oxide film 15 is formed onto the substrate through selective oxidation by using the mask. Since the polycrystalline silicon film 12 is left onto the silicon oxide film 11 on field oxidation, there is no possibility in which a white ribbon is generated near the interface between the silicon oxide film 11 and the field oxide film 15. Accordingly, a gate oxide film 16 can be shaped in a clean state, thus preventing the lowering of gate breakdown strength.

Title: Angular velocity detector
Inventor: KOBAYASHI SHINJI
IPC: G01C19/5719
Filed: 1996-09-25
Abstract: PROBLEM TO BE SOLVED: To enhance detection sensitivity of angular velocity in an angular velocity detector by providing a corrective vibration generating means for correctively vibrating a vibrator in the direction of detection axis to restrict leaked vibration generated in the direction of the detection axis when no angular velocity is applied. SOLUTION: Vibration generating sections 33 and 33 and displacement detecting sections 34 and 34 are respectively arranged on the left and right of a vibrator 26 while corrective vibration generating sections 35 and 35 are arranged longitudinally. In a state where the vibrator 26 is caused to vibrate as indicated by the arrow (a) in the direction of X axis as axis of vibration, leaked vibration in the direction of the Y axis as detection axis as generated when no angular velocity Ω is applied about an axis to be detected is canceled by a corrective vibration generated by the corrective vibration generating section 35. This lowers the leaked vibration working on the vibrator 26 thereby achieving accurate detection of angular velocity Ω.
