Novel thermoplastic polyhydroxyether-based compositions for use as a laser-releasable composition for temporary bonding and laser debonding processes are provided. The inventive compositions can be debonded using various UV lasers, leaving behind little to no debris. The layers formed from these compositions possess good thermal stabilities and are soluble in commonly-used organic solvents (e.g., cyclopentanone). The compositions can also be used as build-up layers for RDL formation.
本发明提供了新型热塑性聚羟基醚基组合物,可用作临时粘合和激光剥离过程中的激光可剥离组合物。本发明的组合物可以使用各种紫外线激光进行剥离,几乎不会留下任何碎屑。由这些组合物形成的层具有良好的热稳定性,可溶于常用的有机溶剂(如
环戊酮)。这些组合物还可用作 RDL 形成的堆积层。
