  • Patent number: 9679184
    Abstract: The present disclosure provides an acoustic wave fingerprint recognition unit including a sensor circuit substrate, a film adhesive layer positioned on the sensor circuit substrate, a piezoelectric material layer positioned on the film adhesive layer and a protection layer positioned on the piezoelectric material layer. The film adhesive layer is formed of a film adhesive material, and the film adhesive material is composed of a film adhesive agent and an organic solvent. The film adhesive agent is an epoxy resin, and the organic solvent is a C3-C8 and carbonyl-containing organic solvent. The solid content of the film adhesive agent in the film adhesive material is in a range of 1%-90%. A method for manufacturing the acoustic wave fingerprint recognition unit is also provided herein.

  • Publication number: 20150086708
    Abstract: A method of processing a substrate or panel is disclosed. A substrate having thereon an array of chips is provided. A mask layer is laminated on the substrate. The mask layer has a plurality of openings to reveal active areas of the chips respectively. A spray-coating process is then performed to form an adhesive film in the active areas. The mask layer is then stripped off.
