As advanced semiconductor processes rapidly transition from 28nm to 3nm and 2nm nodes, more frequent chemical cleaning procedures are driving an increase in demand for liquid chemical waste treatment. Techzone Chairman Chen Li-Li said that semiconductor companies are currently pursuing two major approaches in response to ESG requirements: first, establishing outsourced waste treatment channels; and second, building in-house zero-waste centers to process waste within their own facilities. Both approaches involve close cooperation with Techzone.
