Abstract

Methods and apparatus are described for creating a multi-die package from a wafer without dicing the wafer into individual dies and reassembling the dies on an interposer. One example method generally includes testing a plurality of IC dies disposed on a wafer; disposing one or more connectivity layers above the plurality of IC dies, the one or more connectivity layers comprising one or more electrical conductors configured to connect together two or more of the plurality of dies in each of one or more groups of the IC dies; dicing the wafer having the one or more connectivity layers disposed above the plurality of dies into sets, each set comprising one or more of the plurality of dies, wherein the dicing is based on the one or more groups having IC dies that passed the testing; and packaging at least a portion of the sets of dies.
