    • PURPOSE: A method for fabricating an LCD array substrate is provided to minimize the content of peracetic acid by using etchant composition, and to prevent the overheat of chain decomposition reaction due to exclusion of hydrogen peroxide. CONSTITUTION: A gate electrode is formed on a substrate. A gate insulating layer is formed on the substrate. A semiconductor layer is formed on the gate insulating layer. A source/drain electrode is formed on the semiconductor layer. A pixel electrode connected to the drain electrode is formed. An etchant composition includes peracetic acid 0.5-5 %, a fluorine-containing compound 0.01-2 %, and water. The electrode is formed by using the etchant composition.
    • 目的:提供一种用于制造LCD阵列基板的方法,以通过使用蚀刻剂组合物来最小化过乙酸的含量,并且防止由于排除过氧化氢而引起的链分解反应的过热。 构成:在基板上形成栅电极。 在基板上形成栅极绝缘层。 在栅极绝缘层上形成半导体层。 在半导体层上形成源极/漏极。 形成连接到漏电极的像素电极。 蚀刻剂组合物包括0.5-5%的过乙酸,0.01-2%的含氟化合物和水。 通过使用蚀刻剂组合物形成电极。
