Optimizing Conditions for Formation of Local Zones for Thermomigration in Silicon

Article Preview

Abstract:

The types of defects occurring during the formation of local zones on the surface of silicon wafers have been established. The dependences of defect formation on the surface from the surface microrelief, thickness of the protective coating of silicon oxide, process temperature, flow rate of the melt, the height of the melt, and the concentration of gallium additives in the aluminum have been determined. The optimum conditions of the process of zones formation have been revealed, and the total relative number of all types of defects has been significantly reduced.
