Title: Recovery method and apparatus of polishing agent
Inventor: KASAI TERUHIKO
IPC: H01L21/304
Filed: 1997-07-23
Abstract: PROBLEM TO BE SOLVED: To raise recovery ratio of a polishing agent having appropriate particle diameters by recovering the polishing agent from a permeation liquid obtained by treating a condensed liquid, which is obtained by subjecting a polishing waste liquid to ultrafiltration treatment, with a precision filtration membrane having pore diameters larger than those of the ultrafiltration membrane. SOLUTION: A polishing waste liquid from a polishing device 10 containing particles of a matter to be polished, a crushed polishing agent, their gel and aggregate is stored in a storage tank 12, and then particles having diameters not larger than a specified pore diameter is separated in a permeation liquid, particles having diameters not smaller than the specified pore diameter is separated and condensed in a condensed liquid and the permeation liquid is discharged out of a system or is reused. The condensed liquid can be circulated to a tank 12 at a raw liquid inflow side, and is circulated from the tank 12 via an ultrafiltration device 14 by batch so as to raise condensation ratio sequentially, and when an appropriate concentration is reached, a chemical is added and then the liquid is supplied to a precision filtration membrane device 16. Large particles having diameters not smaller than a specified diameter is separated and removed by the precision filtration filter membrane 16 and then the permeation liquid is recovered as a polishing agent so as to be used in the polishing device 10. Presence of large-sized particles in the recovered polishing agent is very small so that possibility of damaging a surface to be polished is largely reduced.
