Electronic Chemicals & Etchants
Specialty chemicals are used to enhance the technological performance and cost efficiency of electronic components and devices to keep pace with the dynamic electronics industry. Semiconductor device fabrication requires a series of complicated steps performed in a highly controlled manner, from cleaning, etching, and photolithography, to chemical-mechanical planarization and wet processing. The number of process steps and material layers increase in accordance with semiconductor engineering complexity.
