Method for manufacturing acoustic wave device


A method for manufacturing acoustic wave devices includes forming power supply lines along boundaries between chip regions on a main surface of a collective substrate on which interdigital transducer (idt) electrodes and pad electrodes are formed; providing substantially frame-shaped first support members, each including a first opening in which one of the idt electrodes is located and including first through-holes in a region in which the pad electrodes are formed; providing second support members outside the first support members; providing a lid member including second through-holes at positions overlapping the first through-holes on top surfaces of the first support members; and forming terminal electrodes in the first through-holes and the second through-holes by electroplating. The collective substrate, the first support members, the second support members, and the lid member form enclosed spaces in which the power supply lines are sealed..

Method of forming a multilayer aggregate of objects


A method of forming a multilayer aggregate of objects in a channel including a liquid, the method including: a) providing objects at first and second superposed regions of the channel, b) obtaining first and second aggregates of objects, optionally by applying transverse acoustic waves, preferably stationary waves, within each region to objects, and c) bringing the first and second aggregates into contact to form the multilayer aggregate of objects by submitting the first and second aggregates to: gravity in absence of acoustic waves, or to acoustic waves, optionally stationary waves, inducing displacement of the first and second aggregates toward each other.. .
