Abstract
A method for continuous, non lot-based manufacturing of integrated circuit (IC) devices of the type to each have a unique fuse identification (ID) includes: reading the fuse ID of each of the IC devices; advancing multiple lots of the IC devices through, for example, a test step in the manufacturing process in a substantially continuous manner; generating data, such as test data, related to the advancement of each of the IC devices through the step in the process; and associating the data generated for each of the IC devices with the fuse ID of its associated IC device.
