Two-dimensional (2D) dopant profiles, in the range of
9×1016
to
3.6×1018atoms∕cm3
, in laser-diffused silicon resistors were obtained using dopant selective etching (DSE) in combination with cross-sectional transmission electron microscopy (TEM) and focused ion beam technique. Compared with conventional DSE/TEM dopant evaluation, the properties of this technique, related to the reliability, reproducibility, and accuracy of quantification of dopant concentration from
9×1016
to
6×1019atoms∕cm3
, have been improved by considering a vector instead of a scalar etching rate, as determined by an etching model and by a novel calibration method. Those evaluated profiles were accurately compared with a numerical simulation based on heat-transfer and diffusion equations.
