    • PROBLEM TO BE SOLVED: To provide a dicing die bonding film and a dicing method.SOLUTION: The present invention relates to a dicing die bonding film, which is able to maintain good workability and reliability in any semiconductor packaging process, such as adhesive property, gap filling property and pick-up property, while controlling burr incidence in a dicing process and this contamination of die, and a dicing method. Specifically, the present invention is characterized by optimizing tensile characteristics of the dicing die bonding film, or carrying out the dicing on the parts of the die bonding film in the dicing process and separating it through an expanding process. Therefore, the present invention may regulate physical properties of films so as to have the maximized adhesive property, pick-up property and gap filling property without any specific restriction, while controlling burr incidence in the dicing process and contamination of die. As a result, workability and reliability in a packaging process may be excellently maintained.
    • 要解决的问题:提供切割芯片接合膜和切割方法。解决方案本发明涉及一种切割芯片接合薄膜,其能够在任何半导体封装工艺中保持良好的可加工性和可靠性,例如粘合性能, 间隙填充特性和拾取性能,同时控制切割工艺中的毛刺发生率和模具的污染以及切割方法。 具体地说,本发明的特征在于优化切割芯片接合薄膜的拉伸特性,或者在切割工艺中对芯片接合薄膜的部分进行切割,并通过扩展工艺进行分离。 因此,本发明可以调节膜的物理性能,从而具有最大化的粘合性,吸收性和间隙填充性,而不受任何限制,同时控制切割过程中的毛刺发生率和模具的污染。 因此,可以极好地保持包装过程中的可操作性和可靠性。
