  • Electromigration testing for reliability in microelectronics
    Electromigration (EM) refers to the transport of metal ions in interconnect lines under the influence of an electric current In this process, electrons transfer their momentum to the metal ions ("electron wind"), which can lead to material displacement, void formation, and ultimately to the failure of interconnect lines
  • Fast electromigration wafer mapping for wafer fab process monitoring . . .
    Electromigration (EM) is one of the important reliability concerns for wafer fab processing in the semiconductor industry Process changes in the wafer fab backend process, which may impact the EM performance, require typically extensive re-qualification effort
  • Electromigration - JEDEC
    This document describes a method to test the electromigration (EM) susceptibility of solder bumps, including other types of bumps, such as solder capped copper pillars, used in flip-chip packages
  • Wafer Level Electromigration Tests for Production Monitoring
    This paper describes the SWEAT test (Standard Wafer-level Electromigration Acceleration Test) which was developed to monitor electromigration susceptibility at the wafer level The test is extremely fast, allowing evaluation of a metal line in less than 15 seconds
  • Lab Capabilities - Qualitau
    Electromigration (EM) Testing: Conducted on both die-level and package-level interconnects We provide low-stress currents down to hundreds of nano-amperes for testing advanced metal lines and vias
  • 1. 4. 2 Accelerated Lifetime Test - TU Wien
    Electromigration lifetime-testing includes precise resistance measurements under accelerated test conditions The electrical resistance of a metal line changes with time under the influence of an electric current
  • Impact of Test-Structure Design and Test Methods for Electromigration . . .
    The ultimate goal of this work is to develop design guidelines for electromigration test structures and to revise existing standard test methods for fast wafer-level and conventional package-level stress testing
  • Evaluation of Electromigration Using the SWEAT Procedure
    SWEAT (Standardized Wafer-level Electromigration Accelerated Test) is an accelerated electromigration test performed on microelectronic metalization on the wafer
  • Electromigration - Wikipedia
    In a laboratory setting, electromigration failure is readily imaged with an electron microscope, as interconnect erosion leaves telltale visual markers on the metal layers of the IC
  • What is electromigration (EM), and how does it affect design?
    Understanding electromigration (EM) is essential in this process We’ll explore the various testing and verification methods used to assess EM reliability, from accelerated life testing to simulation-based approaches
