Composite Sheet For Protective-Film Formation |
| 摘要 |
A composite sheet 1 for forming a protective film which includes: a pressure sensitive adhesive sheet 2 obtained by laminating a pressure sensitive adhesive layer 22 on one surface of a base material 21; a protective film-forming film 3 laminated on the pressure sensitive adhesive layer 22 side of the pressure sensitive adhesive sheet 2; and a pressure sensitive adhesive layer 4 for jigs, the layer being laminated on a peripheral portion on the opposite side of the pressure sensitive adhesive sheet 2 side of the protective film-forming film 3, wherein a thickness of the pressure sensitive adhesive layer 22 of the pressure sensitive adhesive sheet 2 is from 1 to 8 μm.;According to the composite sheet 1 for forming a protective film, it is possible to effectively suppress loosening of the sheet 1 in the heating step and the cooling step, and the dicing and picking up processes can also be performed satisfactorily. |
