  • Patent number: 7880278
    Abstract: Warpage and breakage of integrated circuit substrates is reduced by compensating for the stress imposed on the substrate by thin films formed on a surface of the substrate. Particularly advantageous for substrates having a thickness substantially less than about 150 ?m, a stress-tuning layer is formed on a surface of the substrate to substantially offset or balance stress in the substrate which would otherwise cause the substrate to bend. The substrate includes a plurality of bonding pads on a first surface for electrical connection to other component.

  • Patent number: 7859090
    Abstract: In one aspect of the invention, a method of attaching a semiconductor die to a microarray leadframe is described. The method comprises stamping an adhesive onto discrete areas of the microarray leadframe using a multi-pronged stamp tool. The adhesive is applied to the leadframe as a series of dots, each dot corresponding to an associated prong of the stamping tool. In some embodiments the adhesive used to attach the semiconductor die to a leadframe is a black epoxy based adhesive material. In an apparatus aspect of the invention, lead traces in a microarray leadframe are arranged to have tails that extend beyond their associated contact posts on the side of the contact post that is opposite a wire bonding region such that such lead traces extends on two opposing sides of their associated contact posts. The tails do not attach to other structures within the lead frame (such as a die attach structure).
