The invention provides a dicing tape integrated wafer back surface protective film, comprising: a crystal strip comprising a base material and a pressure sensitive adhesive layer formed on the base material; and a wafer back protective film, The film is formed on the pressure-sensitive adhesive layer of the dicing tape, wherein the wafer back surface protective film is colored. The colored wafer back surface protective film preferably has a laser marking capability. The dicing tape integrated wafer back surface protective film can be applied to a flip chip mounted semiconductor device. |
