In this paper the technique of infrared angular spectroscopy applied to the characterization of epitaxial layers of n-type silicon grown on N+ or P+ substrates is illustrated. Some results are reported and discussed concerning films having a free-carrier concentration ranging from 1014 cm−3 to 1017 cm−3 and thickness of the order of 10 μm. A significant comparison with results obtained by other techniques (four-point probe, spreading resistance, C−V plots, etc.) is performed and a few simple conclusions are drawn.

Abstract
In this paper the technique of infrared angular spectroscopy applied to the characterization of epitaxial layers of n-type silicon grown on N+ or P+ substrates is illustrated. Some results are reported and discussed concerning films having a free-carrier concentration ranging from 1014 cm−3 to 1017 cm−3 and thickness of the order of 10 μm. A significant comparison with results obtained by other techniques (four-point probe, spreading resistance, C−V plots, etc.) is performed and a few simple conclusions are drawn.File in questo prodotto:
