120results about How to "Improve test throughput" patented technology

A system and method for testing and calibrating integrated sensor devices that improves the manufacturing test throughput of the devices. The system includes a tester, a temperature controller, and at least one probe station including a thermal chuck. The chuck can be heated to specified temperatures to achieve variable heating of a wafer, PCB, or pallet disposed thereon. The temperature controller adjusts the temperature of the chuck to a first specified level. The tester performs at least one first measurement of the output offset of each integrated sensor embodied as a die on the wafer, or as a device on the PCB or pallet. Next, the temperature controller adjusts the temperature of the chuck to a second specified level, and the tester performs at least one second measurement of the output offset of each integrated sensor at the second temperature level. The offset temperature coefficient (OTC) of each sensor is calculated based upon the output offset measurements performed at the first and second temperature levels, and optimal settings for calibrating the respective sensors are determined based upon the calculated OTC values. After the temperature of the chuck is brought back down to the first specified level, the tester programs the output offset calibration settings into each sensor.

An Application Specific Distributed Test Engine (ASDTE) that provides an optimized set of test resources for a given application. The test engine resources, configuration, functionality, and even the number of test engines can be changed as different devices are tested, or as different test methodologies are used with the system. This can be done by including the test engine configuration as a part of the application files that are loaded during the system set-up. This approach differs from conventional testing systems which limit testing to a fixed, limited, or standard stimulus/response engine configuration intended to test a variety of devices. Some of the benefits of the Application Specific Distributed Test Engine Architecture include: (1) a very high test throughput, (2) the ability to adapt system functionality and capabilities to meet different and new, unforeseen device test requirements on a lot-by-lot basis on a production test floor, and (3) the ability to change the number of test engines to optimize tester channels and system utilization.

A method for identifying potentially defective integrated circuit chips and excluding them from future testing as wafers move through a manufacturing line The method includes data-collecting steps, tagging the chips on wafers identified as potentially bad chips based on information collected as the wafer moves down the fabrication line, evaluating test cost savings by eliminating any further tests on the tagged chips preferably using a test cost database. Considering all the future tests to be preformed, the tagged chips are skipped if it is determined that the test cost saving is significant. Tagging bad chips is based on various criteria and models which are dynamically adjusted by performing the wafer final test on samples of the tagged chips and feeding-back the final test results. The dynamic adaptive adjustment method preferably includes a feedback loop or iterative process to evaluate financial tradeoffs when assessing the profit of salvaging chips against the additional test costs.

A coarse-fine two-stage leak detection is carried out on sealed, filled containers loaded into container holders or “pucks”. Failure of the first, coarse leak detection stage, e.g. a pressure-course or impedance or laser-absorption based leak detection stage, causes containers to be rejected together with their corresponding container holders. These are then separated, and the container holder is cleaned and dried before being returned to the system. Any leaking product from inside a grossly leaking container is thus retained within the container holder, thus reducing contamination of subsequent containers and their container holders, preventing such contamination from reaching the fine leak detection stage, e.g. a mass-spectrometer-based leak detection stage.
