Abstract:
A mask-integrated surface protective film, containing: a substrate film, and a mask material layer provided on the substrate film; wherein the mask material layer is an ethylene-vinyl acetate copolymer resin, an ethylene-methyl acrylate copolymer resin, or an ethylene-butyl acrylate copolymer resin; and wherein the thickness of the mask material layer is 50 μm or less.

Claim (Index 8):
A mask-integrated surface protective film used in a production of a semiconductor chip comprising the following steps (a) to (d), wherein the mask-integrated surface protective film has a substrate film and a mask material layer provided on the substrate film, and the thickness of the mask material layer is 50 \u03bcm or less:\n (a) a step of, in the state of having laminated a mask-integrated surface protective film on the side of a patterned surface of a semiconductor wafer, grinding the backing-face of the semiconductor wafer; laminating a wafer fixing tape on the backing-face side of the ground semiconductor wafer; and supporting and fixing the wafer to a ring flame; (b) a step of, after peeling the substrate film from the mask-integrated surface protective film thereby to expose the mask material layer on top, forming an opening by cutting a portion of the mask material layer corresponding to a street of the semiconductor wafer with a laser; or\n a step of, after forming an opening at a street of the semiconductor wafer by a laser cutting of a portion of the mask-integrated surface protective film corresponding to the street of the semiconductor wafer, exposing the mask material layer on top by peeling the substrate film from the mask-integrated surface protective film; \n (c) a plasma-dicing step of segmentalizing the semiconductor wafer at the street with SF 6  plasma, and thereby for singulating the semiconductor wafer into semiconductor chips; and (d) an ashing step of removing the mask material layer with O 2  plasma.
