本申请要求于2020年9月30日提交中国专利局、申请号为202011060818.4发明名称为“一种正性光敏聚酰胺酯树脂及应用其的组合物”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本申请涉及聚酰胺酯树脂技术领域,特别是涉及一种正性光敏聚酰胺酯树脂及应用其的组合物。
聚酰亚胺(PI)薄膜具有耐高低温、耐腐蚀、高绝缘、低介电常数和低介电损耗、力学性能优异、耐化学腐蚀及辐射等优点,广泛用于半导体制造过程的芯片表面钝化、IC电路多层布线的层间绝缘、先进微电子封装(BGA、CSP、SiP、WLP等)的封装基板信号线分配、α-粒子屏蔽层,微焊球的制球工艺,塑封电路的应力缓冲层,柔性封装基板以及液晶平板显示器的制造工艺等方面。在这些应用中,PI薄膜一侧的电子线路往往需要与薄膜另一侧的电子线路实现电气连接,形成导电通道。这种导电通道是将聚酰亚胺薄膜通过光致通孔或激光通孔技术形成的,而光致通孔技术需要采用光敏性聚酰亚胺树脂来实现。
随着移动设备、人工智能、5G通信等高科技领域的快速发展,推动着微电子设备朝着高性能,多功能,小型化的方向发展。为了保持高的信息传输速率,减少信号之间的干扰和感应耦合,降低能量消耗及调制过程中的信号失真,希望介质材料的介电常数进一步降低,介电损耗进一步减小。传统的光敏性聚酰亚胺树脂由于较强的电荷转移络合相互作用和范德华相互作用而形成较高的堆砌密度,而使得介电常数难以进一步的降低。Hoyle等(C.E.Hoyle,D.Creed,P.Subramaian.Polym Prep,1993,34:369)报道,将含氟二胺与含氟二酐聚合生成PI树脂,氟含量增加时,聚合物的介电常数下降。这是由于在PI树脂主链结构中引入氟原子降低了电子极化效应,且随着氟含量的增加,体系的自由体积分数增加,致使介电常数随之线性下降。而对于正性光敏聚酰亚胺而言,其优势就是优异的分辨率和碱性显影液显影的环保特性,而增加氟元素的量会带来显影上的困难。
