Accelerating 14nm device learning and yield ramp using parallel test structures as part of a new inline parametric test strategy

Abstract

This paper will look at both technical and business advantages of parallel vs. serial inline parametric testing, secondary effects of changing test strategies, quantifying return on investment of newer test strategies, and next steps in pushing the envelope of test. Topics such as cost, schedule, macro design and quality will be explored to understand tradeoffs and synergies of test strategies. Examples and metrics of parallel compared to serial testing will be examined.
