Canon’s new nanoprint lithography software will take years to rival the EUV tools that ASML alone offers to make the world’s most superior semiconductors, analysts informed EE Instances.
Canon final week started selling its FPA-1200NZ2C nanoimprint software that stamps a masks with a circuit sample onto a silicon wafer. That tech differs from the optical mechanism completely utilized in ASML EUV instruments to challenge a sample onto a masks.
The Canon know-how faces a number of hurdles, together with an absence of precision and potential restrictions on gross sales of the tools to China, consultants informed EE Instances.
“With nanoimprint know-how, it is going to be very powerful to be on par with what EUV can attain by way of high quality,” stated Cedric Rolin, a program supervisor with semiconductor R&D group imec. Nanoimprint’s stage of defectivity is “fairly excessive,” he stated.
For at the very least two years, ASML’s place might be secure because the world’s solely provider of lithography tools able to making chips on the 2-nm node and past, stated Gaurav Gupta, VP of analysis at Gartner.
He added that the Canon tools is more likely to be topic to export controls which have blocked China’s use of high-end lithography.
“If it really works, and yield and throughput has been labored by, I might anticipate at the very least two to a few years or extra earlier than it’s adopted in high-volume manufacturing,” he stated. “That is assuming it does what’s being promised. From my expertise with such transformative bulletins, it’s for much longer earlier than we see indicators of execution.”
Canon’s press assertion stated its nanoimprint know-how permits patterning with a minimal linewidth of 14 nm, equal to the 5-nm node. With additional enchancment of masks know-how, nanoimprint lithography will allow circuit patterning with a minimal linewidth of 10 nm, which corresponds to the 2-nm node, the corporate stated.
Gupta stated proof of the tech will include business adoption:
“I might get extra confidence as soon as a chipmaker deploys it after which comes out and says yield and throughput are equal or shut to standard lithography. Additionally, if it will possibly do 5-nm node, meaning it will possibly do 28-nm or 14-nm nodes simply. How come somebody in Japan or wherever else hasn’t but adopted it? Whether it is that promising, why wait to make the know-how prepared at 5-nm logic solely, why not at an older or mature node, the place it might need been simpler?”
Nanoimprint might have potential purposes in memory-chip manufacturing, which is extra tolerant of defectivity points than logic, Robert Maire, president of Semiconductor Advisors, stated in a e-newsletter offered to EE Instances. Nanoimprint runs at decrease decision and is much from being a “actual world,” high-volume manufacturing resolution, he added.
“Defectivity and alignment have been perpetual issues and limitations of nanoimprint,” Maire stated. “We do applaud Canon in making glorious progress, by the relentless engineering that Japanese corporations are identified for, however primary technical limitations nonetheless stay.”
One benefit of the nanoimprint software is its smaller carbon footprint, Canon stated.
Because the new product doesn’t require a light-weight supply with a particular wavelength, it will possibly scale back energy use considerably in contrast with photolithography tools, the corporate stated. ASML’s EUV tools consumes massive quantities of vitality to vaporize tin droplets that emit EUV mild with a particularly brief wavelength of 13.5 nanometers.
Canon purchased a number of the nanoimprint know-how when it acquired Molecular Imprints of Texas in 2014, Maire famous. That might make the Canon software topic to U.S. export controls on delicate know-how to China.
The Japanese authorities’s cooperation with the U.S. on export controls will even restrict China’s capability to amass the know-how, Gupta stated.
“If it in any respect seems that the know-how is strong and mature sufficient to help modern logic, I’m positive the united stateswill be capable to work with the Japanese authorities so as to add it, inside limits, on exports to China.”
