Abstract: PURPOSE:To prevent strain in a silicon oxide film in an element isolating region, by using an IVD method, by which nitrogen ion implantation and silicon evaporation are carried out at the same time, and depositing a silicon nitride film on a silicon substrate, in which a silicon oxide film as surface protecting film is patterned and formed in an element isolating region beforehand. CONSTITUTION:Thermal oxidation of a P-type silicon substrate 8 is performed, and a silicon oxide film 9 as a protecting film is formed. An opening part 10, which is to become an element isolating region, is formed by etching. Then, nitrogen ions having low accelerating energy are implanted by an IVD method, and silicon is evaporated with an electron beam at the same time. Thus a silicon nitride film 11 is deposited. At this time a silicon nitride film 12 is formed. The silicon nitride film 11 is etched back, and the film 11 is made to remain only at the opening part 10. The silicon oxide film 9 is removed by wet etching. An impurity ion implanted layer 13 at the element isolating region is formed on the upper surface of the substrate 8. High temperature oxidation is performed, and a silicon oxide film 14 is grown and formed on the layer 13. Then, the flat element isolating region C and an element forming region D, almost free of bird's beak, are formed.

Filed: 1989-04-14
Abstract: PURPOSE:To facilitate closed loop driving by setting the power conduction angle of each phase of a stepping motor smaller than 180 deg. and determining the excitation switching timing of each phase with reference to a point where the sign of counter electromotive force of each phase changes. CONSTITUTION:When the power conduction interval of rectangular waves 50a, 50b is set to 120 deg. which is smaller than 180 deg., power conduction pause intervals of 30 deg. are provided at the opposite ends of a 180 deg. interval between the cross points 51, 52 with the time axis. Power interruption pause intervals of 30 deg. are also provided for the third phase. Since 30 deg. power conduction pause intervals are provided at the opposite ends of the cross point 52, counter electromotive forces of first and third phases can be observed in the interval. Point 54 lagged by 30 deg. from the point where a counter electromotive force 48 detects the cross point 51 is set to be the power conduction starting point of first phase and a point 55 lagged farther from the cross point 51 by 160 deg. is set to be the power conduction finish point. Excitation of a stepping motor is switched at a point where torque can be produced with highest efficiency when the rotor rotates.

IPC: H01B12/06
Filed: 1987-04-18
Abstract: PURPOSE:To provide the vicinity of the surface of a superconductive ceramic with the same superconducting characteristics as those or the interior of the ceramic, by a method wherein a film is formed on the surface of the ceramic and with the film oxidized to be modified into an insulating film, a solid phase- solid phase diffusion is performed in the oxygen of the film to be dissolved a state of shortage of oxygen in the vicinity of the ceramic surface. CONSTITUTION:A superconductive ceramic is formed and is used is a starting material 1. For example, an atmosphere is once evacuated to a vacuum state to deair the oxygen in the vicinity 1 ' of the surface. Then, an Al film 2 is formed on the upper surface in a thickness of 30 Angstrom  by a vacuum deposition method. Moreover, the whole is heated in oxygen in a state, such as in a pressing state for 5 hours at 600 deg.C. The Al film 2 is oxidized and is modified into an Al oxide film 3 and at the same time, oxygen is diffused in the superconductive material from the interior of the Al oxide film. As a result, the oxygen concentration in the vicinity of the surface becomes the same oxygen concentration as that in the interior in spite of a fact that the oxygen is ready- deaired.
