The package level stress-induced voiding (SIV) test of Cu dual-damascene line–via structures is performed. Two different dielectrics, undoped silica glass (USG) and carbon doped oxide (CDO), are used in this work. After 1344 h of high temperature storage test, the resistance drift of USG interconnec...
