style="text-indent:25px">普通的光刻膠在成像過程中，由于存在一定的衍射、反射和散射，降低了光刻膠圖形的對比度，從而降低了圖形的分辨率。隨著曝光加工特征尺寸的縮小，入射光的反射和散射對提高圖形分辨率的影響也越來越大。為了提高曝光系統(tǒng)分辨率的性能，人們正在研究在曝光光刻膠的表面覆蓋抗反射涂層的新型光刻膠技術(shù)。該技術(shù)的引入，可明顯減小光刻膠表面對入射光的反射和散射，從而改善光刻膠的分辨率性能，但由此將引起工藝復(fù)雜性和光刻成本的增加。伴隨著新一代曝光技術(shù)（NGL）的研究與發(fā)展，為了更好的滿足其所能實現(xiàn)光刻分辨率的同時，光刻膠也相應(yīng)發(fā)展。先進曝光技術(shù)對光刻膠的性能要求也越來越高。山東數(shù)字光刻一般的光刻工藝要經(jīng)歷硅片表面清洗烘干、涂底、旋涂光刻膠、軟烘、對準(zhǔn)曝光、后烘、顯影、硬烘等工序。</p><div
