Hydrogen is used in crystal growth and contrast preparation, oxidation process, epitaxial process and chemical phase deposition (CVD). The semiconductor industry has extremely high requirements for gas purity, and the "doping" of trace impurities will change the surface activity of semiconductors. When silicon uses hydrogen chloride to generate chlorine trichloride SIHCI3, it is separated through a separation process and reduced with hydrogen at high temperature to achieve the purity required by the semiconductor: SIHCI3+H2----Si+3HCI. The purity requirements for hydrogen in the process is very high. The traces of carbon monoxide and carbon dioxide impurities contained in hydrogen can oxidize the substrate and generate polysilicon. If it contains methane, silicon carbide will enter the outer layer and cause defects. In the past, silicon external delay required oxygen content to be less than 1*10-6 and dew point to be lower than -70C. Now the requirements are more stringent. Hydrogen generation by water electrolysis can better meet the high requirements of the semiconductor industry for hydrogen.
