Task 2. Accomplishments & Plans
Fatigue test structures characterized, showing feasibility of method and important materials-dependent details of failure
Calculations quantify resolution of in-situ stress measurement; circuitry and overall implementation design in progress (p1)
Prototype in-situ structure defined based on existing tunneling tip device; environmental issues for circuitry being addressed
Improve hard-/soft-ware for fatigue measurements to increase data acquisition rates, greater cycles and testing frequency
Collect and analyze more fatigue data for Aluminum layers
Develop fatigue model in collaboration with Task #1 (f1)
Investigate on-chip fatigue testing for increased frequency range
