  • Patent number: 11541477
    Abstract: An ultrasonic bonding device includes a stage and an ultrasonic horn. A first flat member and a second flat member to be bonded are placed on the stage. The ultrasonic horn includes a press part to be pressed on a laminated portion of the first flat member and the second flat member. The stage includes a lower-side surface, a higher-side surface, and a step wall surface. The first flat member is to be placed on the lower-side surface. The higher-side surface is positioned higher than the lower-side surface by a predetermined step height. The second flat member is to be placed on the higher-side surface. The step wall surface is positioned in a boundary between the lower-side surface and the higher-side surface.

  • Patent number: 11267071
    Abstract: An ultrasonic bonding head includes a vibrator unit, a holder, and a pressurizing shaft. The vibrator unit includes a press part formed at a tip of the vibrator unit in a longitudinal axis thereof and configured to press a bonding scheduled part to be bonded. The holder holds a base of the vibrator unit in a cantilever manner so that the tip is a free end. The pressurizing shaft is connected with the holder and transmits a force of pressing the press part against the bonding scheduled part so that the vibrator unit moves substantially perpendicularly to the longitudinal axis. The holder is provided with a restraint portion. The restraint portion contacts with the vibrator unit at a counterforce dispersion position located between a main hold position for holding the vibrator unit by the holder and the free end.

  • Patent number: 11167541
    Abstract: An apparatus for manufacturing an element array includes a substrate hold means, a laser radiation device, and a collection mechanism. The substrate hold means holds a substrate including an adhesive layer on which elements are attached in a predetermined array while a surface of the adhesive layer is inclined relative to a horizontal surface at a predetermined angle. The laser radiation device radiates a laser to a specific element among the elements attached on the adhesive layer. The collection mechanism is disposed below the substrate and configured to receive the specific element falling by the laser radiation.
