IC Packaging

Once produced, bare die can be assembled by attaching it to a substrate or “packaged” through different processes. ISI has qualified a variety of stacked bare die techniques. These processes are available for use with standard die and do not require custom die or through-silicon vias (TSV). Below are the various die-stacking methods offered for bare die assembly.
