摘要： PROBLEM TO BE SOLVED: To stably and efficiently carry out long-term regeneration treatment of a development waste liquid that contains resist exfoliation and tetraalkylammonium hydroxide (TAAH).SOLUTION: Acid is added to the development waste liquid containing resist exfoliation and TAAH to adjust the liquid to pH 8-9.5, and then membrane separation treatment is carried out by an MF membrane module 1. A permeated liquid is subjected to membrane separation treatment at a liquid permeation temperature of 40-80°C by a nanofiltration (NF) membrane module 2 with a molecular weight cutoff of 200-900 and treated in an activated carbon column 3. Setting the liquid permeation temperature of the NF membrane to 40-80°C lowers the viscosity of the treated liquid and suppresses an operating pressure to increase the amount of permeated liquid. When the amount of permeated liquid of the NF membrane is increased, the resist exfoliation leaks to the permeated liquid side of the NF membrane. However, since the resist exfoliation can be eliminated in the activated carbon treatment in a subsequent stage, a regenerated liquid of high TAAH purity can be obtained.
摘要翻译：要解决的问题：为了稳定有效地进行含有抗蚀剂剥离的显影废液和四烷基氢氧化铵（TAAH）的长期再生处理。
解决方案：将酸加入到含抗蚀剂剥离的发泡废液和TAAH中以将液体调节至pH8-9.5，然后通过MF膜组件1进行膜分离处理。将渗透液体进行膜通过分子量截留值为200-900的纳滤（NF）膜组件2在40-80℃的液体渗透温度下进行分离处理，并在活性炭柱中处理3.将NF膜的液体渗透温度设定为 40-80℃降低处理液体的粘度，并抑制操作压力以增加渗透液体的量。当NF膜的渗透液量增加时，抗剥离层泄漏到NF膜的渗透液侧。然而，由于在后续阶段的活性炭处理中可以消除抗蚀剂剥离，所以可以获得高TAAH纯度的再生液体。版权所有（C）2013，JPO＆INPIT

An addition means 10 is installed in the pre-stage, post stage, or apparatus itself of an ozone dissolving apparatus 4, ozone water in which carbon dioxide or an organic compound is dissolved is used in a use point 7 from a branch pipe 6 through supply piping 11, and ozone in excess ozone water which is not taken out is decomposed by an ozone decomposing apparatus 8. In this way, the self-decomposition of ozone in ozone water is controlled to reduce its consumption so that ozone water of constant concentration can be supplied to a use point after long distance transportation.
