  • Abstract
    Two new preparation methods of silicon substrates in the observation of micro-joint and micro-bumps failure mode were proposed in this study. One method is to use tilted grinding on 3DIC substrate to navigate the failed micro-joints. The other method can provide wider cross-section range by using ion polishing system studied in iST.
