摘要： A cleaning agent and a cleaning process for efficiently removing noxious halogen-based gases such as fluorine, chlorine, boron trifluoride, boron trichloride and tungsten hexafluoride from exhaust gases from semiconductor fabrication processes. The cleaning agent is produced by adherently adding alkali metal formate and/or alkaline earth metal formate to activated carbon, or adherently adding alkali metal hydroxide and/or alkaline earth metal hydroxide together with alkali metal formate and/or alkaline earth metal formate to activated carbon. By exposing exhaust gases to the cleaning agent, noxious halogen-based gases in the exhaust gases are efficiently removed with little desorption of halogen-based gases adsorbed on the cleaning agent. Also, the cleaning treatment is further improved in safety and efficiency by a pre-treatment cleaning agent comprising a metal oxide or a metal hydroxide and a post-treatment cleaning agent prepared by adherently adding sodium formate to a metal oxide.
摘要翻译：一种用于从半导体制造工艺的废气有效地除去有害的卤素基气体如氟，氯，三氟化硼，三氯化硼和六氟化钨的清洁剂和清洁方法。清洁剂是通过将碱金属甲酸盐和/或碱土金属甲酸盐附着在活性炭上，或将碱金属氢氧化物和/或碱土金属氢氧化物与碱金属甲酸盐和/或碱土金属甲酸盐附着在活性炭上而制得的。通过将废气暴露于清洁剂中，废气中有害的卤素基气体被有效地去除，吸附在清洁剂上的卤素基气体很少被解吸。此外，通过包含金属氧化物或金属氢氧化物的预处理清洁剂和通过将金属氧化物附着在甲酸钠中制备的后处理清洁剂进一步提高了清洁处理的安全性和效率。

摘要： A cleaning agent and a cleaning process for cleaning a harmful gas containing, as a harmful component, an organometallic compound represented by the general formula: Rm—M—Hn wherein R is alkyl; M is As, P, S, Se or Te; and m and n are each positive integer satisfying the relation: m+n=valence of M are described. The cleaning agent contains, as an effective component, copper (II) oxide or a mixture of copper (II) oxide and manganese dioxide. The copper (II) oxide has a BET specific surface area of 10 m2/g or greater which is extremely larger than that of copper (II) oxide conventionally used as the effective component of known cleaning agents. With such an extremely large BET specific surface area, the cleaning agent strongly and stably adsorbs the harmful organometallic compound, thereby efficiently cleaning the harmful gas without causing desorption of the adsorbed organometallic compound.
