  • Patent number: 5049434
    Abstract: A pre-patterned device substrate device-attach transfer tape is described which allows a one step mounting of adhesive patterns on a device substrate in the desired configuration for later mount of surface mounted devices (e.g., semiconductor dies) thereon. The tape product contains the adhesive pattern in a mirror image to that desired on the exposed surface of the device substrate. The product of the present invention is utilized by bringing the tape product into contact with the device substrate so that the adhesive on the carrier film bonds to the desired surface of the device substrate thereby bringing the adhesive patterns into the desired configuration desired on the device substrate. The use of pressure and, possibly, heat preferentially bonds the adhesive to the device substrate and allows for later stripping of the support film from the support film/adhesive/device substrate composite.

  • Patent number: 5030308
    Abstract: The bonding of semiconductor chips to a substrate is described wherein the first step involves the bonding of a tacky, curable and partially cured chip bonding adhesive, which is releasably supported on a support film, to the surface of the chip intended to be bonded to the substrate. The second step involves the further partial heat curing of the adhesive to convert it to a non-tacky state so that the adhesive will not undesirably stick during handling and storage operations. Thereafter, the chip with its adherent adhesive can be mounted to a substrate at elevated temperature to convert the adhesive to a more tacky state. The final step involves the curing of the adhesive after it has been used to bond the chip to the substrate.
