Photosensitive polyimide (PSPI) has a unique role in semiconductor packaging, among them, ester-type PSPIs containing acrylic acid derivatives are widely used in industry. Generally, the PSPIs are synthesized by the well-established chloride method, but chloride ions are introduced during the synthesis process, which negatively affects the reaction apparatus, resin purification, and the environment. For the development of green and reliable synthesis methods, we explored the reaction process for the preparation of hydroxyethyl methacrylate PSPI by polyisoimide using 4,4′-diaminodiphenyl ether (ODA) and 4,4′-biphenyl ether dianhydride (ODPA) as the polymerized monomers. The effect of solid content, solvent, and reaction temperature on the gel formation during the synthesis process of PSPI was discussed. The photolithographic and thermo-mechanical properties of PSPI prepared by the polyisoimide method were investigated. The results demonstrate that the PSPI prepared by this method has good photolithographic patterning ability (for a film with thickness of 4.5 μm, circular holes can be opened at a diameter of 15 μm, and the film retention rate is ≥90%) and excellent thermal properties and mechanical properties (Td5%=471℃, Tg=297℃, and tensile strength is 127.5 MPa). There are no Cl-ions introduction during synthsis process, and the process is green and friendly, and simplified with a short reaction cycle. The method was extended to the preparation of other four PSPI systems, and the isomerization method is found to be universal, and this efficient and green synthesis method provides theoretical guidance for the preparation of high-performance PSPI photoresists in laboratories and enterprises.

光敏聚酰亚胺(PSPI)在半导体封装领域具有独特的作用,其中含丙烯酸衍生物的酯型PSPI在工业中得到了广泛应用。这类PSPI通常以相对成熟的酰氯法合成,但在合成过程中酰氯化反应会引入氯离子,对反应装置、树脂纯化以及环境保护造成负面影响。为发展绿色可靠的合成方法,本文以4,4′-二氨基二苯醚(ODA)和4,4′-二苯醚二酐(ODPA)为聚合单体,探索异构化法制备甲基丙烯酸羟乙酯PSPI的反应过程。讨论反应的固含量、溶剂、温度对PSPI合成过程中凝胶形成的规律,并研究异构化法制备的PSPI的光刻性能及其热力学性能。结果表明:该方法制备的PSPI具有良好的光刻图形化能力(4.5 μm厚膜可开15 μm直径的圆孔,留膜率≥90%)、耐热性能和力学性能(Td5%=471℃,Tg=297℃,拉伸强度为127.5 MPa),同时不引入氯离子,过程绿色友好,工艺简单且反应周期短。将该方法拓展到其他4种PSPI树脂体系的制备,发现异构化法具有普适性,这种高效且绿色环保的合成方法为实验室和企业制备高性能PSPI光刻胶提供了理论指导。
