Abstract:
A method of preparing semiconductor dies from a semiconductor wafer having a plurality of fabrication regions separated by dicing lines on the top side of the wafer, and an adhesive coating on the back side of the wafer, comprises applying a repellent material to the fabrication regions and dicing lines where the adhesive coating is not intended to be printed; applying the adhesive coating to the back side of the wafer; removing the repellent material; and separating the wafer along the dicing lines into individual dies.
Abstract:
A wafer backside coating compositions comprises an epoxy, a resin with ethylenic unsaturation, and a reactive sulfur compound and is effective to reduce delamination during reflow operations.

Abstract:
A process for coating a semiconductor wafer with a coating composition comprises curing the coating with a pulsed UV light, thereby preventing delamination during reflow operations. In a particular embodiment, the coating composition comprises both epoxy and acrylate resins. The epoxy resin can be cured thermally; the acrylate resin is cured by UV irradiation.
Abstract:
For use in a DMFC, a proton-conducting membrane containing a proton- conducting host polymer and a functionalized fullerene having one or more proton accepting or proton donating functional groups selected from: >C[PO(OH) 2 ] 2 ; - PO(OH) 2 J-OH; -SO 3 H; -NH 2 ; -CN; -HOSO 3 H; -COOH; -OPO(OH) 2 ; and -OSO 3 or a combination of two or more of these groups attached to the fullerene.
Abstract:
A multi-layer barrier adhesive is used for the encapsulation of electronic devices, such as organic light-emitting diodes (OLEDs), photovoltaics, and thin-film transistors. The multi-layer adhesive comprises at least one barrier layer disposed adjacent at least one adhesive layer. In one embodiment the barrier layer is a fluoropolymer. The fluoropolymer is preferably a homopolymer of tetrafluoroethylene (PTFE) or chlorotrifluoroethylene (PCTFE), or their copolymers.
