摘要
One of the main issues in the characterization of silicon on insulator (SOI) substrates is to determine the quality of the film-buried oxide interface. This interface quality is strongly connected to the carrier lifetime in the silicon film. In this paper, we extend the well-known pseudo-MOSFET characterization technique for SOI wafers to the extraction of carrier lifetime. The experiment consists in comparing the drain current measured under dark and under laser shining. A model is proposed to evaluate the surface recombination velocity in SOI. Experimental results are validated by numerical simulations. (C) 2013 AIP Publishing LLC.
