An adhesive tape for wafer dicing is provided with an adhesive layer on a base material film. The adhesive layer is composed of two or more layers, and a resin composition constituting either adhesive layer includes a radiation polymerization compound. A content of the radiation polymerization compound in the resin composition constituting an outermost layer of the adhesive layer and that in a resin composition constituting the inner side adhesive layer are different to a degree to sufficiently transmit a stress applied on the base material film to the outermost layer after the radiation irradiation to separate the layer from a chip. A chip manufacturing method using such adhesive tape is also provided.
(ZH) 本发明涉及一种在基材薄膜上设置了粘合剂层的晶片切割用胶粘带,包含2层以上的该粘合剂层,构成任一粘合剂层的树脂组合物都含有可辐射聚合的化合物,同时,构成粘合剂层中最外层的树脂组合物所含有的可辐射聚合的化合物的含量和构成内侧粘合剂层的树脂组合物所含有的可辐射聚合的化合物的含量不同,并达到使施加在基材薄膜上的应力被充分传递到放射线照射后的最外层以充分剥离该层和芯片的程度,本发明还提供使用该晶片切割用胶粘带的芯片的制造方法。
