What Are Electronic Wet Chemicals?

Wet electronic chemicals are one of the important supporting materials in the electronics industry. Their quality not only affects the yield, electrical performance and reliability of electronic products directly, but also has an important impact on the industrialization of advanced manufacturing technologies, with high product added value and technical threshold.

Definition and Classification of Wet Electronic Chemicals

Wet electronic chemicals, also known as ultra-clean and high-purity reagents or process chemicals, refer to the main component purity greater than 99.99%, generally requiring the control of impurity particle size below 0.5m, and metal impurity content below ppm level (ppm for 10-6, ppb for 10-9, ppt for 10-12).

Wet electronic chemicals are key basic chemical materials in the electronics industry and one of the important supporting materials. They are various liquid chemical materials used in the wet process of microelectronics and optoelectronics.

Wet electronic chemicals can generally be divided into general wet electronic chemicals (usually ultra-clean and high-purity reagents) and functional wet electronic chemicals (usually mixed reagents). At present, the market demand is dominated by general-purpose wet electronic chemicals, accounting for about 70% of the demand. General-purpose wet electronic chemicals: generally single-component, single-function chemicals, such as hydrogen peroxide, hydrogen peroxide, sulfuric acid, etc.

Functional wet electronic chemicals: Refers to compound chemicals that achieve special functions and meet special process requirements in manufacturing by means of compounding, such as developing solution, stripping solution, etching solution, cleaning solution, etc.
