摘要: To speed up the pattern generator which is a bottleneck for speedup of an LSI tester, a continuous address control information for generating addresses for continuous pattern memory read is generated at a speed 1/N (N is an optional number larger than 1) times the operation speed of the continuous address generator, and the address controller is divided into a 1st and a 2nd address controller. The two controllers are connected via a buffer memory to ensure the normal operation when the correspondence between address control instructions and patterns to be continuously read is not 1:N. Continuous address information generated by the 1st address controller is stored in the buffer memory. The second address controller, which actually generates continuous addresses, receives the continuous address information from the buffer memory, outputs the addresses to the pattern memory at a speed N times of the operation speed of the 1st address controller, and receives the next continuous address information from the buffer memory once again when the continuous address generation is finished to repeat the operation mentioned above.

摘要: An electrostatic vibrator has a vibrating plate including beam-shaped vibrating parts each fixed at opposite ends thereof and configured for electrostatic actuation to perform flexural vibration, and temperature compensation parts connected to the vibrating parts. A silicon oxide film covers each of the vibrating parts but not the temperature compensation parts. A substrate is mounted in parallel relation to the vibrating plate. An oxide layer is disposed between the substrate to the vibrating plate. Electrodes are formed on the substrate and arranged on opposite sides of each of the vibrating parts.

摘要: A silicon oxide film 113 is formed on the vibrating parts 102 and 103 of an MEMS-type electrostatically-actuated flexural vibrator. At least one structure where no oxide film is formed is provided near the vibrating parts 102 and 103. By employing a structure in which both ends of the structure and both ends of the vibrating parts 102 and 103 are integrally formed, a compressive stress is applied to the vibrating parts 102 and 103. As a result, the frequency temperature characteristics can be improved.
