Abstract
The present invention provides a dicing tape-integrated wafer back surface protective film including: a dicing tape including a base material and a pressure-sensitive adhesive layer formed on the base material; and a wafer back surface protective film formed on the pressure-sensitive adhesive layer of the dicing tape, in which the wafer back surface protective film is colored. It is preferable that the colored wafer back surface protective film has a laser marking ability. The dicing tape-integrated wafer back surface protective film can be suitably used for a flip chip-mounted semiconductor device.
