Image Theses and Dissertations An improved method for determining impurity concentration profiles of epitaxial silicon slices as a function of distance from the surface by the incremental capacitance-voltage method Impurity concentration in epixtaxial layers frequently vary with distance from the substrate. It is important to be able to measure these profiles with precision though out the entire epitaxial layer. View Item

Image Theses and Dissertations A measuring system for continuous plotting of the doping profile of a semiconductor wafer A measuring system developed by J. A. Copeland to directly plot the doping profile of a semiconductor wafer, has been built to facilitate the research group at Lehigh University engaged in semiconductor device. The technique involves generation of the second harmonic voltage obtained by driving a Schottky diode with a small constant RF current on the order of a few hundred microamperes at a fundamental frequency of 4.5 MHz.
