光刻的基本原理是:利用光致抗蚀剂(或称光刻胶)感光后因光化学反应而形成耐蚀性的特点,将掩模板上的图形刻制到被加工表面上。光刻半导体晶片二氧化硅的主要步骤(见图)是:①涂布光致抗蚀剂;②套准掩模板并曝光:③用显影液溶解未感光的光致抗蚀剂层;④用腐蚀液溶解掉无光致抗蚀剂保护的二氧化硅层;⑤去除已感光的光致抗蚀剂层。
光致抗蚀剂是一种对光敏感的高分子溶液,种类很多,根据光化学反应的特点一般可分为正性和负性两大类。凡用显影液能把感光的部分溶解去除的称为正性光致抗蚀剂;用显影液能把未感光的部分溶解去除的称为负性光致抗蚀剂。
光刻的精度很高,可达微米数量级,为使蚀刻线条清晰、边缘陡直、分辨率小于1微米的超微细图形,可采用远紫外曝光、X射线曝光、电子束扫描曝光,以及等离子体干法蚀刻等新技术。
