Semiconductors are materials with conductive properties that lie between those of conductors and insulators (such as silicon Si, germanium Ge, and silicon carbide SiC). Through doping processes, their conductivity can be altered to produce basic electronic components such as transistors and diodes, which are then integrated to form integrated circuits (ICs / chips), enabling functions such as signal processing, storage, and computing. 

High-purity valve and pipe fittings are the core components for fluid transportation and control in the semiconductor manufacturing process. They directly determine the purity, stability and yield of high-purity medium transportation as well as the chip manufacturing process. Yiteng high-purity valve and pipe fittings meet strict requirements such as high purity, low leaching, zero leakage and resistance to strong corrosion.
