Nikon Corporation announced today a Joint Development Program with CEA-Leti, one of Europe's leading microelectronics research centers focused on optical lithography development for technology beyond 45 nm. The work will examine the potential of Double Exposure and Double Patterning for 32 nm semiconductor devices, and will utilize a leading-edge Nikon scanner located in CEA-Leti's Nanotec 300 research facility.

Nikon and CEA-Leti Announce Partnership for Double Patterning and Double Exposure Technology

BELMONT, CA | Posted on February 27th, 2007

Double Patterning was added to the ITRS roadmap in 2006 as a potential solution for 32 nm lithography. EUVL and high-index immersion are also listed as potential solutions on the ITRS roadmap, but the development timeline for those technologies may limit them from being used for 32 nm applications. Nikon is working with key research centers and leading-edge IC manufacturers, as well as partnering with design, mask, and resist companies to ensure a manufacturable solution is available in time for the 32 nm node.

"CEA-Leti offers an outstanding, state-of-the-art facility with all of the processes required for Double Patterning," stated Toshikazu Umatate, Executive Officer, Precision Equipment Company, Nikon Corporation. "Our collaboration with Leti enables us to leverage their process expertise and our lithography knowledge to develop the best exposure tools and processes for this challenging technology."

"The partnership with Nikon is a great opportunity to develop all aspects of Double Processing with one of the world's leading equipment suppliers," said Olivier Demolliens, head of the Nanotec Division at CEA-Leti. "DE/DP is the main solution foreseen for the 32 nm node, bridging the gap between immersion and EUV, but there are still a lot of issues that need to be addressed on equipment, process, mask and CAD. Together with Nikon equipment and expertise, we have built a consortium that will address all these developments."
