Title:
BASE MATERIAL FILM FOR DICING FILM AND DICING FILM
Document Type and Number:
Japanese Patent JP2016162787
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a dicing film which is excellent in expandability and recoverability and can be used without the generation of wrinkle and sag and without adhesion to a stage even when thermal hysteresis is applied to a semiconductor wafer.SOLUTION: In a base material film for a dicing film including a base material layer 41 and a surface layer 42 that is arranged on one main surface of the base material layer, the base material layer includes a polymethylpentene resin. In the base material layer, the content of a polymethylpentene resin is preferably 60 mass% or more and 95 mass% or less, and an olefin elastomer is preferably included.SELECTED DRAWING: Figure 4
