摘要:
A computer-implemented system and method for capability zone-based manufacturing quality control are provided. A specification for manufacturing a part feature is obtained, the specification including a nominal and a tolerance. A plurality of measurements for the feature are obtained. A difference is determined between the nominal and each of the measurements. The difference for each of the measurements is compared to the tolerance. Each of the measurements is assigned into one of a plurality of capability zones of measurements based on the comparison. Visual representations of the capability zones into which the measurements were assigned are displayed.

The invention proposes a system that interrupts a processing associated with an ADC having low priority when an ADC processing cannot catch up with ADR by an ADC alone that is not under execution but uses an ADC for an ADR having high priority. To preferentially execute ADR/ADC having high priority, the invention employs an algorithm for serially selecting ADR/ADC in the order of higher processing capacity (in the order of greater numerical values in the expression by a DPH unit) from among ADR/ADCs that have the lowest priority, no matter whether the ADR/DC is now under execution or not.

A manufacturing cell for inspecting workpieces such as magnetic disk substrates comprises an input conveyor for providing workpieces to be tested, one or more testers for inspecting the workpieces, and three or more output receptacles for receiving tested workpieces. One or more robotic arms move the workpieces from the input conveyor to the tester and from the tester to one of the output receptacles depending upon the results of the test performed by the tester. The output receptacles include a pass receptacle, a reject receptacle, and at least an additional receptacle for workpieces that are to be re-worked or studied further. If the additional receptacle is full, workpieces that would otherwise be provided to the additional bin are placed in the reject receptacle. The reject receptacle is very large, so that it is rarely filled to capacity.

A test control system for controlling overall test procedures which processes test data generated from the final test process and analyzes bin category results. The control system uses testers for testing electrical characteristics of IC devices, a host computer for processing data transmitted from the testers and for creating a number of database structures, and distributed computers for monitoring the test progress and analyzing the test results using the database structures stored in the host computer. A control method using the control system includes the steps of: performing a final test as a lot; monitoring the status of the final test progress while storing test data during the final test; determining if the final test is completed; performing a lot decision after the final test is completed based on bin category limits; and displaying the lot decision result and storing the test data. The lot decision is based upon any bin category having a bin capacity exceeding its bin category limit by greater than a certain predetermined value even though the lot meets the yield requirement. As a result, the control system can detect an abnormal lot more easily than a system in which the lot decision is based only on yield.

A computer-implemented system and method for part surface manufacturing quality control are provided. A specification for manufacturing a part surface is maintained in a storage, the specification comprising a target value for a profile characteristic of the surface. Measurements of the profile characteristic of the surface produced during multiple manufacturing runs are maintained in the storage, wherein the surface produced during each of the manufacturing runs is associated with two or more of the measurements made at different points of the surface. A score for each of the measurements is calculated based on how the close that measurement is to the target value. For the surface produced during one or more of the manufacturing runs, the scores for at least some of the measurements made for that surface during that manufacturing run are displayed.

摘要:
A method and system sorts manufactured integrated circuit devices by evaluating performance characteristics of the manufactured integrated circuit devices. All of the integrated circuit devices are manufactured using an identical design, and differences in the performance characteristics among the integrated circuit devices occurs because of variations including manufacturing line variations. The integrated circuit devices are sorted into groups according to the performance characteristics and are utilized in different computing devices depending upon individual performance requirements of the computing devices.
