A cleaning agent which comprises 0.1 to 60% by weight of an oxidizing agent and 0.0001 to 5% by weight of a chelating agent. In the process for producing semiconductor integrated circuits, a pattern layer of a photoresist used as an etching mask and residues formed from the photoresist by dry etching can be easily removed with the cleaning agent. In the process for producing substrates for liquid crystal display panels, residues derived from a conductive thin film formed by dry etching can also be easily removed. In the cleaning processes using the cleaning agent, wiring materials or insulating materials in thin film circuit devices or other materials used for producing substrates of semiconductor integrated circuits and liquid crystal panels are not corroded.
                            一种清洁剂,由 0.1%至 60%(按重量计)的氧化剂和 0.0001%至 5%(按重量计)的
螯合剂组成。在生产半导体集成电路的过程中,作为蚀刻掩膜的光刻胶图案层和通过干法蚀刻从光刻胶上形成的残留物可以很容易地用清洁剂去除。在生产液晶显示屏基板的过程中,通过干法蚀刻形成的导电薄膜的残留物也很容易去除。在使用清洁剂的清洁过程中,薄膜电路装置中的布线材料或绝缘材料或其他用于生产半导体集成电路和液晶面板基板的材料不会被腐蚀。
