Claim One:
1. A method of selecting a plurality of golden devices from among a plurality of test devices fabricated on a plurality of chips carried on a golden wafer in order to extract parameters for a device model, the method comprising: measuring numerical values of at least one single point characteristic for first and second test devices of a different geometry on each of the chips on the golden wafer; performing a statistical analysis of the numerical values of the at least one single point characteristic measured for the first and second test devices; applying a selection criterion to the statistical analysis of the numerical values for the first and second test devices to identify respective first and second golden devices with numerical values nearest to the selection criterion; performing an electrical characterization of the first golden device and of the second golden device; and extracting one or more parameters from the electrical characterization of the first and second golden devices for use in the device model.
