Abstract:
1. A method for tracking at least one integrated circuit device comprising: providing each integrated circuit device of a plurality of integrated circuit devices with at least one identification code in a lot of integrated circuit devices of a plurality of lots of integrated circuit devices; reading the at least one identification code of each integrated circuit device of the plurality of integrated circuit devices in a lot of integrated circuit devices of a plurality of lots of integrated circuit devices; advancing the plurality of integrated circuit devices through a manufacturing process in a substantially continuous manner after mixing at least one integrated circuit device of the integrated circuit devices from one lot to another lot of the plurality of lots of integrated circuit devices without regard to the lot of the plurality of lots from which the integrated circuit devices come during the manufacturing process; generating data related to the advancement of each integrated circuit device of the plurality of integrated circuit devices through at least a portion of the manufacturing process; and associating the data generated for each integrated circuit device of the plurality of integrated circuit devices with the at least one identification code for an associated integrated circuit device of the plurality of integrated circuit devices.
