INDEXING OF ELECTRONIC DEVICES DISTRIBUTED ON DIFFERENT CHIPS |
| 摘要 |
A method for indexing electronic devices includes: forming first chips in a first wafer, forming 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. 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. |

1. A method for indexing electronic devices, comprising:
forming a plurality of first chips in a first wafer, forming a plurality of second chips in a second wafer, forming a plurality of electronic devices in a composite wafer, each electronic device comprising one first chip coupled to one corresponding second chip, and forming an index for each electronic device, the index being indicative of a position of the electronic device on the composite wafer, by:
forming a first portion of the index on the first chip, andforming a second portion of the index on the second chip. |
