Chips individually encrypted during fabrication

Leti and Mapper, an equipment manufacturer based in the Netherlands, recently announced a major innovation: an individual security code etched onto the metal interconnects of individual chips during fabrication. Mapper developed a multiple electron beam maskless lithography test machine, which Leti integrated into a standard 40 nm CMOS fabrication process. The machine can be adapted to other technologies, on 200 mm or 300 mm wafers.

Each individual chip’s code can be accessed, but not modified. This type of chip could bring benefits to cybersecurity, traceability, and counterfeit prevention. Mapper is in talks with several manufacturers interested in testing the encryption technology on their wafers.
