    摘要: A material for purification of a semiconductor polishing slurry that without changing of pH value, is capable of efficiently purifying a polishing slurry to thereby not only prevent metal contamination of a polished object as effectively as possible but also achieve recycling of a polishing slurry without any problem; a relevant module for purification of a semiconductor polishing slurry; and a process for purifying a semiconductor polishing slurry with the use thereof. In particular, a material for purification of a semiconductor polishing slurry characterized in that it comprises a fibrous substrate having a functional group capable of forming a metal chelate or such a functional group together with hydroxyl fixed onto at least the surface thereof. This material for purification of a semiconductor polishing slurry is, for example, used in such a manner that it is inserted in a container fitted with polishing slurry inflow port and outflow port while ensuring passage of polishing slurry flow.

    摘要: A thread-reinforced paper sheet comprises upper and lower paper layers and a reinforcing thread interposed therebetween. A thread-reinforced gummed tape comprises a tape base material which consists of upper and lower paper layers and a reinforcing thread interposed between the upper and lower paper layers, and a moisture activated adhesive layer formed on one of surfaces of the tape base material. In each of the thread-reinforced paper sheet and the thread-reinforced gummed tape, a water-soluble or water-dispersible adhesive is used to laminate the upper and lower paper layers, and a water-soluble thread is used as the reinforcing thread. Each of such thread-reinforced paper sheet and such thread-reinforced gummed tape exhibits a strength equivalent to that of the prior art article and moreover, has a complete disintegratability. Thus, a regeneratable thread-reinforced paper sheet as well as a regeneratable thread-reinforced gummed tape is provided.
