Title: Method for adjusting characteristic frequency of biaxial- vibration structure
Inventor: RI KIBAN
IPC: G01C19/5769
Filed: 1996-05-22
Abstract: PROBLEM TO BE SOLVED: To establish a method for adjusting the frequency of a biaxial vibration structure by measuring the natural frequency thereof in the directions of X-axis and Y-axis and adjusting the natural frequency in the direction of Z-axis while fixing the natural frequency in the direction of X-axis. SOLUTION: In order to ensure the performance of a biaxial vibration structure 12, the natural frequency must be adjusted by varying the natural frequency in the direction of Z-axis while fixing the natural frequency in the direction of X-axis. When the thickness is altered at a narrow spring part 14 or 16 while taking account of the shape of structure, the spring coefficient is altered in both axial directions. On the contrary, when the thickness is altered at a wide spring part 15, the spring coefficient can be altered in the direction of Z-axis without substantially altering the spring coefficient in the direction of Z-axis. Consequently, when the thickness is altered at a wide spring part 15, the spring coefficient can be adjusted in the direction of Z-axis while fixing the natural frequency in the direction of X-axis.

Abstract: PURPOSE:To enable to remove the stepped section on an insulating film caused by underlayer wirings as well as to prevent the breaking of wire by a method wherein damage is formed on the surface of the interlayer insulating film located between the upperlayer and the lowerlayer wirings. CONSTITUTION:An Mo wiring layer 1 and an SiO2 film 3, having the prescribed pattern, are provided on a substrate 2. The damage is given on the surface of the SiO2 film by exposing the surface to the plasma of SiF4, a resist 5 is formed on the film with the pattern reverse to the Mo 1, and the SiO2 on a certain part of the Mo only is exposed. The resist 5 is slightly superposed on the Mo 1. The SiO2 film 3 is etched approximately in the same degree as the Mo 1. As the surface of the SiO2 film 3 is damaged, it has a poor adhesive property, it is etched from the interface also and the taper angle alpha is turned to approximately 20 degrees. When the resist film 5 is removed, the SiO2 film 3 having almost flat surface appears. If an Al layer 4 is formed on the film 3, a multilayer wiring wherein no breaking of wire is generated will be obtained.
