Hi all,
I wanted to know the meaning of "Parameter Extraction" in semiconductor device modeling. (Say for instance. MOSFET). Could somebody explain in detail about this detailing the steps.
Many thanks.

The parameter extraction of circuit models of semiconductor devices is an important step in the cycle of electronic design, . The goal of parameter extraction (PEX) is to determine the device model parameters that minimize the differences between a set of measured characteristics and the device model. Although most device models are based on physical theory, there are always some parameters which do not have physically-defined values, and others for which the physical values do not give the best fit to real device characteristics. Thus it is generally necessary to extract model parameters from measured transistor data.
