Applications in Semiconductor

Hydrogen is used in crystal growth and contrast preparation, oxidation process, epitaxy process and chemical deposition (CVD).The semiconductor industry has a high requirement for gas purity. The "incorporation" of trace impurities will change the surface activity of semiconductors.When SIHCI3 is generated from silicon by hydrogen chloride, it is separated by fractionation process and reduced by hydrogen at high temperature to meet the purity requirement of semiconductor: SIHCI3+H2----Si+3HCI. The purity requirement of hydrogen is very high in the above process.The impurities of carbon monoxide and carbon dioxide in hydrogen will oxidize the substrate and form polysilicon. If it contains methane, it will form silicon carbide into the outer layer, causing defects. In the past, the oxygen content was less than 1 * 10-6 and the dew point was lower than - 70c, but now it is more demanding.Hydrogen production by water electrolysis can meet the high requirements of semiconductors for hydrogen.
