  • METHOD OF RESTRICTING CHIP MOVEMENT UPON BONDING TO RIGID SUBSTRATE USING SPRAY COATABLE ADHESIVE
    Publication number: 20110318882
    Abstract: A method of bonding a chip to a wafer at precise alignment suitable for fabricating a heater chip in an ink jet printhead is provided. The method includes spray coating an adhesive composition on a surface of a substrate, aligning and tacking at least one chip to the substrate coated with the adhesive composition, exposing the substrate tacked with at least one chip coated with the adhesive composition to radiation and heat, and performing thermal compression bonding. The method uses a spray coatable adhesive composition comprising a thermally activated adhesive and a photoacid generator.
