Abstract
An example method of tracking information for integrated circuits (ICs) that are handled by a plurality of tools during manufacture includes: marking each of IC with a barcode after the ICs have been packaged; performing, at a first tool of the plurality of tools, one or more electrical tests of the ICs and storing electrical characteristics of each IC in association with the barcode of each IC in a database; querying the database with a specification to obtain a set of barcodes for candidate ICs having electrical characteristics that match the specification; scanning, at a second tool of the plurality of tools, the barcode of each of the ICs to select a plurality of ICs each having a respective barcode in the set of barcodes; and segregating the plurality of ICs from the ICs.
