    • A dicing die bond film suitable for processing a thin film wafer is provided to remove a chip flying effect by increasing fixing force to a ring frame. A dicing die bond film includes a supporting base layer, an adhesive layer, and a fixing adhesive layer. The adhesive layer includes a lower adhesive layer(32) and an upper adhesive layer(22). The lower adhesive layer is laminated on the supporting base layer. The upper adhesive layer is laminated on the lower adhesive layer. The peel strength between the lower adhesive layer and the ring frame is 0.007N/mm to 1.000N/mm. The peel strength between the upper adhesive and the fixing adhesive layer is 0.002N/mm to 0.020N/mm after the peel strength. Further, the upper adhesive layer contains 30-90 wt.% of acryl copolymer, 10-70 wt.% of acryl compound and 0.1-10 wt.% of photoinitiator based on 100 wt.% of the upper adhesive layer.
    • 提供适于处理薄膜晶片的切割模片接合薄膜,以通过增加对环形框架的固定力来消除芯片飞行效应。 切割芯片接合膜包括支撑基底层,粘合剂层和固定粘合剂层。 粘合剂层包括下部粘合剂层(32)和上部粘合剂层(22)。 下部粘合剂层层压在支撑基底层上。 上粘合剂层层压在下粘合剂层上。 下粘合剂层和环形框架之间的剥离强度为0.007N / mm至1.000N / mm。 剥离强度后,上粘合剂和固定粘合剂层之间的剥离强度为0.002N / mm至0.020N / mm。 此外,上粘合剂层包含基于100重量%的上粘合剂层的30-90重量%的丙烯酸共聚物,10-70重量%的丙烯酸化合物和0.1-10重量%的光引发剂。
