Auger electron spectroscopy characterization of Ti/NiV/Ag multilayer back-metal for monitoring of Ni migration on Ag surface
Capability of Auger analysis to detect low concentration of contaminants element. Nickel migration on surface is very well observable. The possibility to have a precise chemical map of the surface, is shown Well results were found in a specific DOEcreated to simulate the thermal stress conditions The purpose is to use AES in order to fix a method to detect and study the problems of die attach imputable to Ni migration.
