The importance of statistical lifetime models for the reliability assessment of semiconductors is increasing steadily, because resources and time are limited. The devices are tested under accelerated electrical and thermal conditions which causes degradation in metal layers. To visualize the damage, Scanning Acoustic Microscopy (SAM) is used. In this work, an approach combining image processing and statistical modeling is presented in order to quantify and predict the damage intensity in SAM images. The image processing algorithm automatically locates and quantifies the maximum damaged areas in SAM images. The damage intensity is coded as an ordered categorical variable and a cumulative link model for damage prediction is defined. Both the algorithm and the proposed statistical model show good results.
