The sheet resistance and junction depth as a function of time at various temperatures have been obtained for the deposition of boron in silicon by using a BBr~ liquid source. A simulation program incorporating a more realistic moving boundary condition is developed to analyze the deposition process under oxidizing atmosphere. By fitting numerical solutions to experimental data, the moving interface velocity and diffusion coefficient are determined. The profile of deposited layers as a function

The solid solubility of boron in silicon as a function of temperature has been determined. Different surface concentrations corresponding to different thicknesses of the boron-rich layer can be explained by the translation of the BRL-Si interface. * Electrochemical Society Active Member.
