Abstract

An accurate method of measuring the two-dimensional doping profile of a semiconductor by measuring an electrical parameter along a path of a dopant iso-concentration. Thin vertical or horizontal slices of the semiconductor integrated circuit are provided and are probed to allow the electrical parameter to be measured through a single concentration area.
