With domestic wafer fabrication capacity coming online, the wet electronic chemicals market keeps expanding rapidly. High-volume, tight-specification products such as ultra-high-purity isopropyl alcohol and electronic-grade hydrogen peroxide attract the most attention in the localization push.
SEMI Grade-5 products require each of 33 metal ions to stay below 1 ppb, alongside strict particle and organic impurity limits. Suppliers must build a complete trace-control system spanning purification, clean packaging treatment, and logistics; qualification typically takes more than a year.
Industry observers believe domestic suppliers with Class-1000 cleanroom filling and end-to-end traceability will win entry into mainstream fab supply chains during the capacity window over the next two years.
