Cost of Test is one of the biggest challenges for the semiconductor test industry today. The development of next generation equipment is driven by the need for increased efficiency. Enhanced tester capabilities allow shorter test times and higher parallelism. Handlers try to keep pace with higher parallelism but mismatch with speed.
Currently, for many applications the tester, the most expensive part of the test cell, is idle, waiting for the handler. The urgent challenge is to optimize tester utilization in order to benefit from higher parallelism and shorter test times.
This presentation will focus on the effects of optimizing those parameters one by one. Additionally it will elaborate on the interdependencies of the parameters and analyze application specific requirements. Finally, it the presentation will postulate new concepts that today’s and future tester generations require to fully leverage their advanced capabilities.
