FILM ADHESIVE AND SEMICONDUCTOR PACKAGE USING THE SAME

摘要

A film adhesive having an adhesive layer (C) mainly containing a thermoplastic polyimide having a glass transition temperature of not more than 100° C. and an adhesive layer (D) having a storage shear modulus of not more than 106 Pa at 50° C. Furthermore, the film adhesive further comprises a base material (A) and an adhesive layer (B). The film adhesive can exhibit excellent low-temperature adhesive property and covering capability functioning as a die bonding adhesive film which can be used in a semiconductor package. In addition, the film adhesive can exhibit excellent low-temperature adhesive property and covering capability which functions both as a die bonding adhesive film and as a dicing tape.
