  • Adhesive paste for semiconductors
    Patent number: 6165613
    Abstract: This invention is an adhesive paste that consists essentially of a polymeric resin in particulate form and a carrier for the resin. The polymeric resin is present as particles with a particles size of 50 microns or smaller, is insoluble in the carrier at ambient temperature, and is soluble in the carrier at a temperature above ambient temperature. The carrier either reacts with the resin to form a covalent bond, or vaporizes from the adhesive paste, at a temperature above the temperature at which the resin is soluble in the carrier. The paste contains no inorganic fillers, holds its geometry on application, and fuses to a void-free bond.
