WebBEOL generally begins when the first layer of metal is deposited on the wafer. BEOL includes contacts, insulating layers ( dielectrics ), metal levels, and bonding sites for chip-to-package connections. After the last FEOL step, there is a wafer … WebOct 17, 2012 · The ISPC-controlled wafers consistently exhibited a much flatter profile following Active Oxide polish compared to the POR open-loop wafers, based on all-die F5 metrology. Zone-to-zone range was improved by more than 300% over pad life for closed-loop wafers (ISPC-control) vs open-loop POR wafers.
