摘要： A method of poling a piezoelectric actuator, which can improve the uniformity of a plurality of piezoelectric actuators. In the method, a plurality of piezoelectric actuators are prepared for poling. Then, at least two preliminary poling processes are performed on the prepared piezoelectric actuators under different preliminary voltages and displacements of the piezoelectric actuators subjected to each of the at least two poling processes are measured. A relationship between a voltage and a displacement for each of the piezoelectric actuators is established. Poling voltages are calculated so that the piezoelectric actuators can have the same target displacement. Formal poling is performed on the piezoelectric actuators under the calculated poling voltages. The displacements of the piezoelectric actuators, which have completed the formal poling, are measured.

摘要： A silicon direct bonding (SDB) method by which void formation caused by gases is suppressed. The SDB method includes: preparing two silicon substrates having corresponding bonding surfaces; forming trenches having a predetermined depth in at least one bonding surface of the two silicon substrates; forming gas discharge outlets connected to the trenches on at least one of the two silicon substrates to vertically penetrate the bonding surface; cleaning the two silicon substrates; closely contacting the two silicon substrates to each other; and thermally treating the two substrates to bond them to each other. The trenches are formed along at least a part of a plurality of dicing lines, and both ends of the trenches are clogged. Gases generated during a thermal treatment process can be smoothly and easily discharged through the trenches and the gas discharge outlet such that a void is prevented from being formed in the junctions of the two silicon substrates due to the gases.
