In the semiconductor industry, the reduction of the devices test time has always been an urgent need to be able to optimize the productivity and reduce the cost of the test. On the other hand, it’s critical to maintain a high level of quality on production by dedicating a part of testing to Quality Assurance check.

Perform the QA check in a dedicated test step, repositioning the devices after the Final Test, however, goes in contrast with the throughput optimization needs.

The inline QA test is performed on the device immediately following the FT test, but under the QA limits and without moving the device. So this technique is increasingly requested by customers who want to guarantee the high quality levels required, together with a reduction in the cost of the test.

Eagle Vision MST and the Productivity Tools for ETS-800 provide all the flexibility that allows us to have an Inline QA solution that can be easily integrated into test programs. In this paper is described this solution for ETS800 Multisite Distributed (MSD) projects, compatible even in single sector condition. It provides all necessary functions and integration instructions within a test program. The QA test will be enabled on the fly, according to a predetermined execution frequency set by the user, performing the quality tests following the FT flow, on a certain device or on more at the same time. To control the QA test execution, the solution will take advantage of the potentials of the new TerMSTApp CsharedDataArray Class to manage communication between the sectors.
