Abstract:
1. A method of making packages for integrated circuit die, the method comprising: providing a semiconductor wafer having a plurality of integrated circuit die formed thereon, each integrated circuit die having a first surface and a second surface opposite the first surface and a plurality of bonding pads formed on the first surface; prior to dicing the semiconductor wafer, selectively applying a curable material over a portion of the first surface of each integrated circuit die formed on the wafer without covering the plurality of bonding pads for the respective integrated circuit die; curing the curable material; dicing the semiconductor wafer to separate the plurality of integrated circuit die from each other; attaching at least some of the separated integrated circuit die to die pads of a lead frame strip; and applying an encapsulant material over the lead frame strip having the integrated circuit die attached; wherein the cured material extends above the encapsulant material.
