Claim One:
1. A method of selecting a plurality of golden transistors from among a plurality of transistors 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 a single point characteristic for a plurality of first transistors of a first geometry and a plurality of second transistors of a different second geometry on each of the chips on the golden wafer; identifying a median of the at least one single point characteristic measured for the first transistors of the first geometry; identifying a median of the at least one single point characteristic measured for the second transistors of the different second geometry; selecting one of the first transistors having the numerical value of the single point characteristic nearest to the first statistical characteristic to be the first golden transistor of the first geometry; selecting one of the second transistors with the numerical value of the single point characteristic nearest to the second statistical characteristic to be the second golden transistor of the different second geometry; performing an electrical characterization of the first golden transistor and of the second golden transistor; and extracting one or more parameters from the electrical characterization of the first golden transistor and the second golden transistor for use in the device model.
