Semiconductors

From the perspective of process procedures, semiconductors are mainly divided into chip design, front-end wafer fabrication, and back-end packaging and testing, among which front-end wafer fabrication is the core process of semiconductor manufacturing. Similar to the flat panel display manufacturing process, the entire wafer manufacturing process needs to go through more than a dozen cleaning, photolithography, etching and other processes, and these steps require the participation of wet electronic chemicals.
