Publication number: 20230080214Abstract: The present invention provides a system and method for analysis of integrated circuit testing anomalies based on deep learning. Through repeated training by deep learning with historical test data accumulated during testing, automatic optimization of parameter settings depending on learning and training conditions is made possible. Moreover, based on real-time test data, testing anomalies can be predicted and early warnings against them can be provided to allow advanced intervention for preventing their occurrence. Additionally, for testing anomalies that have occurred, solutions can be automatically identified and provided, which shorten the times taken by different technicians to address the anomalies, resulting in more effective utilization of the equipment and lower testing cost.Type: ApplicationFiled: August 31, 2021Publication date: March 16, 2023Inventors: Kun YU, Zhiyong ZHANG, Jianhua QI, Yi WU, Yongjia WU, Yong NIU

Publication number: 20200309845Abstract: The present invention relates to an optimization method for an integrated circuit wafer test, which is applied in an integrated circuit wafer test process. By means of pre-specifying and storing coordinates of a die to be tested on a wafer in a test system, then testing the pre-specified die according to a design map by means of a test process, and adjusting in real time a range of pre-specified coordinates according to a test result of a current die, a desired test coordinate map is finally obtained so as to cover the maximum number of fail dies in an optimized solution, thereby reducing test time, improving testing efficiency, reducing the frequency of testing hardware usage and increasing service life. By means of calculating a suitable coverage number in the present invention, a smaller number of fail chips that reach a package will also be obtained without increasing the cost of the package. At the same time, the number of probe card tests is reduced, and the hardware service life is increased.Type: ApplicationFiled: April 2, 2018Publication date: October 1, 2020Inventors: Hua Wang, Zhiyong Zhang, Jianbo Ling, Jianhua Qi, Yuanhua Liu, Haiying Ji
