The development of photovoltaic technology has increased the demand for gas in the electronics industry. Such as chemical vapor deposition (CVD)Or physical vapor deposition (PVD), these technologies are mainly used to manufacture semiconductors or photovoltaic cells. Nitrogen trifluoride (NF3), silane (SiH4) and ammonia are used in semiconductors, liquid crystal displays (LCDS). And photovoltaic technology in the field of the three main electronic industrial gases.
