摘要
This paper presents a modified excess carrier profiling technique using carrier decay cross-sectional scans of wafers using a narrow excitation fiber guided beam and by using infrared light as well as microwave probes. The theoretical principles of the technique are based on the analysis of the depth variation of decay shape and the amplitude. (C) 2001 Elsevier Science Ltd. All rights reserved.
