Demand for silicon and wafers is rising rapidly, fuelled in particular by the fast-growing solar market and the steady expansion of the semiconductor industry. From raw silicon to the final wafer, large amounts of argon, hydrogen and nitrogen are required along the entire process chain. In addition, polysilicon and wafer manufacturers need electronic gases and chemicals that comply with the most stringent purity and consistency standards. At the same time, cost and environmental pressures call for greater process efficiencies.
