Filed: 1990-10-12
Abstract: PURPOSE:To improve breakdown strength and to achieve the compact size by providing a diaphragm having the opening part for introducing pressure and having the cavity of a specified size in the inside on a single-crystal semiconductor substrate. CONSTITUTION:A sacrifice layer which is formed on a P-type silicon substrate 2 is etched. A cavity 5 is formed at the lower surface of an N-type epitaxial layer 3 which is formed on the sacrifice layer. Thus a diaphragm part 6 is formed. The cavity 5 is made larger than a pressure-introducing opening part 4. The etching time can be shortened by isotropic etching. The surface of silicon which is to become a connecting part with a base and which is not etched can be kept at the perfect mirror state. Airtightness in electrostatic bonding can be improved. The displacement amount of the diaphragm part 6 can be made small by making the sacrifice layer thin. High breakdown strength can be reinforced when excessively high pressure is applied, and the epitaxial layer can be made thin. Therefore, sensitivity can be improved, and miniaturization can be achieved.

Filed: 1996-10-16
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus and a method in which a vibration test to be executed by combining a partial vibration test with a vibration response numeral analysis can be executed under a wide-range vibration condition. SOLUTION: A reaction force from a structure 2, to be tested, which is vibrated by an exciter 6 is measured by a reaction-force measuring means 9. Data on the reaction force and data on an external force meaning an earthquake or the like are input to a vibration-response analytical function part 13 at intervals of every constant time, an exiciter-displacement computing function part 14 which receives its analyzed result computes an exciter displacement to be added to the exciter 6. An exciter-displacement compensation function part 15 executes a compensation corresponding to an exciter dynamic characteristic. On the basis of the compensated exciter displacement (computed value), an exciter-driving-signal computing function part 16 computes an exciter- displacement estimated value. The estimated value is used as a driving signal so as to drive the exciter 6. Thereby, since the computed result of the exciter-displacement computing function part 14 agrees with an actual displacement applied to the structure 2 to be tested, an error due to the exciter dynamic characteristic is eliminated, and a vibration test can be performed with high accuracy.
