Electronic Wet Chemicals refer to chemical reagents with a purity greater than 99.99%, used in wet processes such as wet etching, cleaning, developing, and stripping. These liquid chemical materials are primarily applied in the integrated circuit (IC), photovoltaic (PV) panel, and display panel industries. Ultra-pure reagents, internationally known as Process Chemicals, are referred to as Wet Chemicals in the United States, Europe, and Taiwan. Their purity and cleanliness are critically important for the yield, electrical performance, and reliability of electronic components.
