Patent ID: 7041736

Claim:
A method of fabricating a device, comprising: fabricating an integrated circuit chip, the integrated circuit chip including a plurality of electrical bond pads; fabricating a substrate; positioning the integrated circuit chip relative to the substrate; providing electrical connection between the integrated circuit chip and the substrate during a reflow operation; providing an underfill composition between the integrated circuit chip and the substrate, the underfill composition including an epoxy; and a curing agent selected from the group consisting of low molecular weight maleic anhydride polymers comprising cyclohexane or bridged cyclohexane having the following structural formula, where n is 0, 2 or 3, n′ is 5 to 50, and R is selected from the group consisting of alkyl, aryl, substituted aryls, esters, ethers, lactones, anhydrides, alcohols, nitriles, epoxy, carboxylic acids and mixtures thereof, maleic anhydride polymers comprising norbornene having the following structural formula: where n is 1, n′ is 5 to 50, and R is selected from the group consisting of ethers, lactones, anhydrides, alcohols, nitriles, epoxy, carboxylic acids, and styrene/maleic anhydride polymers having a molecular weight of about 1600 g/mole, and mixtures thereof.
