ESD/Latch-up Analysis Test Service

At development stage, we obtain actual data of ESD and latch-up immunity of LSIs and, in case of failure event, we offer everything from analysis to reliable improvement measures. ESD and Latch-up tests are important reliability tests for mass production.

When ESD and Latch-up defects occur, proposed measures based on analysis involve revision of mass production schedule to safeguard the prototype period. Furthermore, analysis, mask repair, trial runs, etc., raise additional cost.

Here, at device development stage, it is important to grasp actual data and identify pending issues. By getting this data acquisition and counter-measures customer will achieve reduction of TAT and can assure stable performance after mass production.

Merits of ESD/Latch-up Analysis Tests

  • Merit 1
    Because during the ESD/Latch-up test we reveal pins in need of improvement and those with excessive tolerance margin, ESD/Latch-up measures as well as optimization is possible at development stage.
  • Merit 2
    Time required for measurement evaluation after ESD/Latch-up test can be shortened by using our company's tester. We also offer preparation of test programs, design of conversion/measurement boards and probe cards.
  • Merit 3
    Should we detect a problem with the device after ESD/Latch-up test, we will provide a combo-test service from analysis to improvement proposal.
