Abstract

This chapter will focus on the metrology steps to support 2.5D and 3D reference flows employing via-mid copper through-silicon via (TSV) processing, wafer thinning, and backside processing using a handle wafer and chip-to-chip bonding. Reference flows that use via formation after thinning or wafer-to-wafer 3D integration will not be addressed.
