Abstract:
A method for encapsulating flip chip interconnects, comprising applying a limited quantity of encapsulating resin to at least interconnect bumps on an interconnect side of a singulated integrated circuit chip, wherein the step of applying resin to the chip comprises providing a reservoir having a bottom and sides, providing a pool of resin in the reservoir to a depth not greater than a bump standoff height, dipping the bumps on the interconnect side of the chip in the resin pool so that bumps on the chip contact the reservoir bottom, and then withdrawing the chip from the resin pool; and thereafter bringing the chip together with a substrate under conditions that result in displacement of encapsulant from between the bumps on the interconnect side of the chip and respective bonding pads on the substrate, and that promote the bonding of bumps with the respective pads.
