Abstract
Methods for selecting one or more golden devices on a golden wafer that exhibit a smooth length and width scaling behavior. Test devices of differing geometry and carried on different chips of the golden wafer are screened with single point measurements of electrical performance. Based upon a statistical analysis of these single point measurements, chips are selected that carry the respective golden device of each given geometry that exhibits optimum electrical performance referenced to a selection criterion. Golden devices identified by the selection process are extensively characterized with a more comprehensive electrical measurement. The parameters derived from these more extensive test measurements on the golden devices are then used for refining a device model for a circuit simulation.
