20100304551 | PROTECTIVE FILM AGENT FOR LASER DICING AND WAFER PROCESSING METHOD USING THE PROTECTIVE FILM AGENT - A protective film agent for laser dicing according to the present invention comprises a solution having, dissolved therein, a water-soluble resin and at least one laser light absorber selected from the group consisting of a water-soluble dye, a water-soluble coloring matter, and a water-soluble ultraviolet absorber. The protective film agent is coated on a surface of a wafer, which is to be processed, and is then dried to form a protective film. Laser dicing through the protective film produces chips from the wafer. As a result, deposition of debris can be effectively prevented on the entire face of the chips, including their peripheral edge portions. | 12-02-2010 |
