Description

一种粘合促进剂及包含其的光敏树脂组合物 技术领域
本发明涉及光刻胶技术领域,具体涉及一种粘合促进剂及包含其的光敏树脂组合物。
背景技术
光刻胶(又称光致抗蚀剂)在光照下可进行光化学反应,将其涂覆在半导体、导体和绝缘体上,经曝光、显影后留下的部分对底层起保护作用,然后采用刻蚀剂进行刻蚀就可以将所需要的微细图形从掩模版转移到待加工的衬底上,是微细加工技术中关键性化工材料,主要用于集成电路、平板显示、LED、PCB及精密传感器等微细加工。
把图形从掩模版转移到晶圆表面是由多个步骤来完成的,大部分的光刻工艺都是从基本光刻十步法的变异或选项。
第一步,表面准备:清洗并甩干基底表面。在集成电路、平板显示器、LED芯片制造过程中,基底材料可以是硅基底、玻璃基底、蓝宝石基底,或在硅基底、玻璃基底、蓝宝石基底上敷设的金属膜、非金属膜、金属氧化物膜、非金属氧化物膜。
第二步,涂胶:在基底表面涂覆一层薄的光刻胶。光刻胶的种类:正胶,比如酚醛与叠氮醌类化合物形成的光刻胶,衬底图形与掩模版图形相同;负胶,如采用聚乙烯醇月桂酸酯等作为光敏材料的光刻胶,在衬底形成的图形与掩模版相反。光刻胶涂胶方法有:刷法、滚转方法和浸泡法。
第三步,软烘焙:通过加热使光刻胶溶剂部分蒸发。比如,热板、对流烘箱、红外烘箱、微波烘箱、真空烘箱。
第四步,对准和曝光:掩模版与衬底对准,使光刻胶曝光。光刻机种类有接触式、接近式、投影式、步进式。曝光光源有紫外UV、深紫外DUV、X射线等。
第五步,显影:去除非聚合物的光刻胶。例如,沉浸式显影、喷雾式显 影、混凝式显影、等离子体去除浮渣。显影液主要为碱性显影液,常用四甲基氢氧化铵水溶液作为显影液,其他碱性显影液也可以用于显影,例如氨水,碱金属氢氧化物,烷基胺,烷醇胺,咕啉,四烷基氢氧化铵等的水溶液。
第六步,硬烘焙:对溶剂的继续蒸发。在设备和方法上与软烘焙类似。对流炉、在线及手动热板、红外隧道炉、移动带传导炉和真空炉都用于硬烘焙。
第七步,显影检查:检查表面的对准和缺陷。
第八步,刻蚀:将衬底顶层通过光刻胶的开口部分去除。包括干法刻蚀和湿法刻蚀。
第九步,去除光刻胶:又称剥离,将彻底上的光刻胶去除。
第十步,最终检查:对于刻蚀的不规则性和其他问题进行表面检查。
例如,LED用蓝宝石芯片生产采用采用PSS(Patterned Sapphire Substrate)技术,也就是在蓝宝石衬底用光刻胶刻出相应图形,之后采用电感耦合等离子体刻蚀技术刻蚀蓝宝石,之后去除光刻胶,再在其上生长GaN材料。光刻胶作为刻蚀阻挡物,必须与衬底表面层黏结很好,才能忠诚的将图形转移到衬底表面,缺乏黏结性将导致图形畸变。
为了提高光敏树脂组合物与基底的粘合性,常在光敏树脂组合物中加入粘合促进剂。例如,CN1802608B中通过加入磺酰基取代的氮化合物或噻重氮化合物。该粘合促进剂的机理是:环氮化合物提高了基底侧的粘合性,磺酰基与酚醛树脂清漆中的羟基产生氢键作用,可以防止显影时碱性物质的腐蚀,防止粘结性下降。该粘合促进剂中含有硫元素,可能对基底产生腐蚀作用,因此需要更温和的粘性促进剂。
发明内容
本专利的目的是:提供一种粘合促进剂,以及包含该粘合促进剂的光敏树脂组合物。该光敏树脂组合物可以用于制造半导体集成电路(IC)、有机发光二极管(LED)、平板显示器(FPD),例如液晶显示器(LCD)、有机发光显示器(OLED)等。
