ABSTRACT:
An inventive 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. By associating the data with the fuse ID's, the inventive method allows the IC devices to be tracked through the step in the process. Further, because multiple lots of the IC devices can advance through the step in the process continuously, manufacturing resources are used more efficiently. In addition, because the fuse ID's and associated data read and generated using the inventive method need not physically accompany IC devices as they progress through the manufacturing process, the inventive method is more reliable than conventional tracking procedures.
