Leti and Mapper Develop Individualized Chips with Maskless Lithoography in CMOS Process

Low-Cost Cyber-Security Breakthrough that Encrypts Individual Chips With a Unique Code Presented at SPIE Advanced Lithography 2018 in San Jose

GRENOBLE, France and DELFT, Netherlands – March 2, 2018 – Leti, a research institute of CEA Tech, and Mapper Lithography, the leading provider of maskless lithography equipment for the semiconductor and nanofabrication industries, today announced a low-cost cyber-security breakthrough that encrypts individual chips with a code.

The non-falsifiable code is generated by using a unique chip design that leverages direct multi-beam writing in a process that fits in a conventional CMOS flow with an extra level of lithography and without photomasks. Throughput on Mapper‘sFLX-1200 tool installed at Leti is compatible with optical systems.

The markets for these chips include data security, traceability and combatting imports of counterfeit chips.

Leti, a specialist in electron-beam lithography, and Mapper, a Dutch company, presented a paper on the breakthrough, “Process development of a maskless N40 via level for security application with multi-beam lithography”, today at SPIE Advanced Lithography 2018 in San Jose, Calif. The paper demonstrates a via patterning integration that is compliant with standard CMOS 40nm process flow.

“Standard optical exposure tools – optical scanners using masks – repeat the identical design on the entire silicon wafer, and cannot fabricate individualized chips,” said Leti’s Isabelle Servin, the lead author of the paper. “Leti applied its deep multi-beam lithography knowhow and Mapper‘s unique maskless fabrication tools to achieve this differentiating, cyber-security chip.”

The maskless lithography system, based on massively parallel electron-beam writing capability developed by Mapper, is designed for high-volume specialty chips and low-volume advanced logic.

Leti and Mapper are demonstrating the breakthrough for their customers at Leti’s facility in Grenoble.
