Claim Text:
1. A method of dicing a semiconductor wafer comprising a plurality of integrated circuits, the method comprising: forming a mask above the semiconductor wafer, the mask covering and protecting the integrated circuits; coupling the semiconductor wafer to a film frame with an ultra-violet (UV)-curable adhesive film; pre-curing a peripheral portion of the adhesive film disposed beyond an edge of the semiconductor wafer, wherein the adhesive film is transmissive of UV light and wherein the pre-curing comprises: patterning the mask with a laser scribing process to provide a patterned mask with gaps, exposing regions of the semiconductor wafer between the integrated circuits; and subsequent to pre-curing the peripheral portion of the adhesive film, etching the semiconductor wafer through the gaps in the patterned mask to form singulated integrated circuits while the semiconductor wafer is affixed to the adhesive film.
