Electronic Chemicals
As a leading supplier of high purity chemicals, General Chemical offers the broadest
line of microelectronic grade wet process chemicals in North America. With purities that extend
to the parts-per-trillion level, our high-quality acids, etchants, specialty solvents (photoresist
developers and strippers, edge bead removers and rinse agents), wafer cleaning chemicals and
custom formulated blends are used by semiconductor device, disk drive and wafer manufacturers
globally. As a basic manufacturer, we are vertically integrated to meet the stringent requirements
of high-tech producers who need the coherent manufacturing, analytical and packaging capabilities
of one supplier.
