Abstract:
A semiconductor package which is free of metal debris from backside metallization (BSM) is disclosed. The semiconductor package is singulated by performing a saw street open process from the frontside of the wafer and then includes a singulation process using a plasma etch from the backside of the wafer with BSM. The singulation process results in metal debris free packages.
