Patent ID: 8278151

Claim:
A method of holding a chip-shaped workpiece that is formed by dicing, comprising providing a tape for holding a chip, wherein the tape has a configuration in which a pressure-sensitive adhesive layer is formed on a base material, wherein the pressure-sensitive adhesive layer has a chip-shaped workpiece pasting region and a frame pasting region, wherein the pressure-sensitive adhesive layer is characterized in that, when the pressure-sensitive adhesive layer is adhered to a silicon mirror wafer, a 180-degree peeling adhesive power of the pressure-sensitive adhesive layer in the frame pasting region is 5 times or more as compared to the 180-degree peeling adhesive power of the pressure-sensitive adhesive layer in the chip-shaped workpiece pasting region when measured at a temperature of 23 ±3° C. and a tensile speed of 300 mm/min; providing a chip-shaped workpiece that has been formed by dicing a workpiece into a plurality of chip-shaped workpieces; pasting a mount frame to the frame pasting region of the tape; and pasting the chip-shaped workpiece to the chip-shaped workpiece pasting region of the tape.
