Metal ion control by ppb basis:
From perfect control of raw materials to verification of resin contact materials of production facility, CHEMWILL have good command of control of contamination, metal ion removing technology.
Our target is standardization of metal ion (such as Na, Fe, Cr, Ni) contents level within several hundreds to few ppb.
We are also challenging to control 24 elements of metal which is required in semiconductors industry.
