Process for reducing the surface recombination speed in silicon

摘要

The reduction of surface recombination is required for the manufacture of electronic devices made of silicon as well as for the application of various measurements and analytical methods for determining the purity of silicon. According to this invention, a process will be described for applying a laquer layer to the surface of silicon wafers, wherby the surface recombination velocity will be reduced to a value below 100 cm/s.
