OCI produces the high-purity phosphoric acid required in semiconductor production.
Product Features

Semi-H3PO4
Usage
Semiconductor wafer etchant material, LCD Etchant Material
Production Process
P4(yellow phosphorus) is combusted and undergoes hydration and refinement to produce phosphoric acid (75%, 85%). Additional refinement is executed to produce high-purity phosphoric acid for semiconductors.
