Abstract: An embodiment of the present invention is a technique to package flip chip molded matrix array package. An ultraviolet (UV) curable tape is laminated on die backside of a strip of array of flip chips. The UV curable tape has an adhesive strength. The strip of flip chip arrays is molded with a mold film. The molded strip of flip chip array is irradiated using UV radiation. In another embodiment, a double functional tape is mounted to backside of a wafer. The double functional tape includes a binding tape and a ultraviolet (UV) curable tape having an adhesive strength. The wafer is singulated into die. The die is attached to a substrate strip to form a strip of array of flip chips. The strip is molded with a mold film. The molded strip is irradiated using UV radiation.

Abstract: A method and apparatus for inhibiting the flow of a flowable adhesive material disposed adjacent to a substrate. A chip component is disposed adjacent to a substrate and a plurality of nanoparticles are disposed and cured adjacent to the substrate and proximate to the chip component. The nanoparticles possess surface properties that make them substantially immiscible with a flowable adhesive. The band of nanoparticles will inhibit the flow of a flowable adhesive material disposed between the chip and the nanoparticles, in a direction bounded by the plurality of nanoparticles, while adhesive flow in the direction of the component is promoted.
