DG: Interconnects
Ever
decreasing dimensions in microelectronic circuit chips lead to two extremes in electromigration testing
- extremely low test currents for the smallest lines
- extremely high test currents for the largest lines The
validity of such a test is limited by external factors e.g. measurement
equipment or non electromigration effects inherent to
the chosen experiment e.g. Joule heating.
In addition the introduction of low k
materials adds concerns due to thermal connectivity and cycling as well as
potential corrosion effects.
These are
challenges to the traditional approach with Black's equation to determine the
interconnect lifetime.
The
Interconnect Discussion Group invites attendees to share their concerns and
knowledge of the topic. Hopefully as a group we can combine our wisdom to find
answers for todays
challenges.
