  • Abstract
    A dedicated new device is proposed to address the electromigration on BEOL (Back-End of Line) at wafer level. A local heat is directly generated around the tested Electromigration via ended Metal line (EVEM) based on a NIST (National Institute of Standard Technology). A coil plays the role of heater and allows separating the temperature stress from the current stress. Black´s parameters obtained and extrapolated lifetimes are closer to package level results. Thermal gradient is minimized and so extrapolated lifetimes are valid.
