Applications in Hi reliability Program of Integrated Circuit Upgrade Test

In this paper,the quality levels of monolithic IC upgrade test and its application in hi reliability program were introduced Some main items of upgrade test includes upscreening test,qualification and quality conformance procedures (group B test) and Destructive Physical Analysis(DPA) The upgrade screening is an efficiency solution for IC quality level,delivery time and fee The procedure and method for reliability upgrade test were studied to provide reference for its application in the projects
