What Are the Critical Water Quality Parameters for Semiconductor Manufacturing? Key Takeaways: – Semiconductor manufacturing requires UPW with resistivity exceeding 18.2 MΩ·cm for advanced process nodes – Total organic carbon (TOC) must remain below 1 ppb to prevent wafer contamination and yield loss – Dissolved oxygen (DO) levels affect oxidation potential in critical cleaning processes…
