Calcium oxide is a basic oxide and reacts with acidic oxides such as silicon dioxide present in the rock. Calcium oxide reacts with silicon dioxide to give calcium silicate. The calcium silicate melts and runs down through the furnace to form a layer on top of the molten iron. It

Diffusion And Segregation Properties Of Iron In Silicon

Iron contamination often originates at the surface of a wafer during processing in the IC fabrication line and is diffused into the wafer during subsequent thermal processing. Since the silicon wafer surface is often passivated with a silicon dioxide layer, comprehensive understanding of iron transport in silicon dioxide is necessary. The goal of this research is to advance the fundamental and ...
