Abstract :
This paper reports a yield model merging critical areas computed by a survey sampling based estimation tool (EYES) and a large set of defectivity measurements performed during the fabrication process at the SGS-Thomson Crolles plant. This model is applied to commercial devices processed in a mature 0.5 μ technology. The robustness of the model was tested with a large number of lots including multiple products, process versions (routes) and defectivity variations
