IPC: H01L21/302
Filed: 1998-09-30
Abstract: PURPOSE: A system and a method for monitoring abnormal waste materials are to determine whether abnormal waste materials are generated by a wet washing process without a damage of wafer. CONSTITUTION: A method for monitoring abnormal waste materials comprises the steps of: irradiating an infrared rays to a washing solution(100) to be used in a wet washing process; detecting a first strength of the infrared rays permeating the washing solution; producing a reference profile representing the first strength; irradiating the infrared rays to the washing solution used in the wet washing process; detecting a second strength of the infrared rays permeating the washing solution; producing a comparison profile representing the second strength; and comparing the reference profile with the comparison profile and determining whether the abnormal waste materials are generated by the wet washing process. An infrared rays source(110) irradiates an infrared rays of a certain frequency range to a washing solution used in a wet washing process at certain strength. A detector(120) detects a strength of the infrared rays permeating the washing solution and converts it into an electrical signal.
