Indexing of electronic devices distributed on different chips

摘要

An embodiment of a method is proposed for indexing electronic devices. The embodiment includes the steps of forming a plurality of first chips in a first wafer, forming a plurality of second chips in a second wafer, forming the electronic devices by coupling each first chip with a corresponding second chip, and forming an index on each electronic device; the index is indicative of a position of the corresponding first chip in the first wafer. In an embodiment, the step of forming an index includes forming a first portion of the index on the first chip, and forming a second portion of the index on the second chip.
