Comparison of effectiveness of Current Ratio and Delta-I/sub DDQ/ tests Conference Paper uri icon


  • I DDQ test is a valuable test method for semiconductor manufacturers. However, its effectiveness is reduced for deep sub-micron technology chips due to rising background leakage. Current two test methods that promise to extend the life of I DDQ test are Current Ratio and Delta-I DDQ. Although several studies have been reported on these methods, their effectiveness in detecting defects has not been contrasted. In this work, we compare these two methods using industrial test data.
