Protective film composition, manufacturing method of semiconductor device, and laser cutting method |
| abstract |
The present invention provides a protective film composition including: a water-soluble resin (A), a laser light absorbing agent (B), and a solvent (C), wherein the water-soluble resin (A) includes a polyvinylpyrrolidone-based water-soluble resin (A-1), and the polyvinylpyrrolidone-based water-soluble resin (A-1) has a K value of 75 or more and 150 or less. The protective film composition has the advantage of good leveling property. |
