Functional electronic wet chemicals are indispensable basic chemical materials for developing, cleaning and etching process of semiconductor manufacturing. They are mainly applied in integrated circuit manufacturing, flat panel display manufacturing and photovoltaic cell manufacturing. Integrated circuit manufacturing The application of functional electronic wet chemicals in integrated circuit manufacturing mainly refers to wafer processing, including the pre-treatment of silicon wafers before wafer processing and backend packaging and testing. The wafer processing is very complex, which can be divided into lithography, etching, oxidation, thin film, chemical mechanical polishing grinding (CMP), diffusion (DIFF) and other parts. Lithography, etching, oxidation and surface pretreatment processes all require functional electronic wet chemicals. Integrated circuit manufacturing Flat panel display manufacturing Flat panel display manufacturing Functional electronic wet chemicals are mainly used in the development, lithography (etching-peeling) and cleaning processes of array process in flat panel display manufacturing. The array process for flat panel display manufacturing is similar to wafer processing, except that array fabricates thin-film transistors on glass instead of silicon wafers. Functional electronic wet chemicals are key basic materials in flat panel display manufacturing. The cleaning of particles and organic matter on the substrate, the development and removal of photoresists, and the etching of circuit require functional electronic wet chemicals. Photovoltaic cell manufacturing The main process of photovoltaic cell manufacturing include texturing, P-N junction preparation, aluminum backplane preparation, front and back metal contact, and anti-reflection layer deposition. Functional electronic wet chemicals are mainly used in the texturing, cleaning and etching of photovoltaic cell manufacturing. The amount of functional electronic wet chemicals used in the texturing processing part accounts for 60%-70% of the total consumption.
