One of the problems of doping profile measurements using CV techniques is that numerical differentiation is required. This can, under certain circumstances, result in very noisy profiles. This paper presents a method of obtaining noise-free profiles by choosing a step size that takes account of the resolution of the capacitance meter to ensure that the maximum profile detail is retained. A range of other factors that can effect profiling accuracy are also reviewed.
