Rapidus CEO Atsuyoshi Koike will get a lift from Japan’s CHIPS Act and IBM to start out the nation’s sole semiconductor foundry making the world’s most superior silicon simply two years behind {industry} heavyweight Taiwan Semiconductor Manufacturing Co. (TSMC), he stated in an unique interview with EE Occasions in Brussels.
Koike and his crew of greater than 100 individuals are taking over the problem of a lifetime.
Koike is a chip-industry veteran who lately labored for Western Digital and based Trecenti, a Japanese foundry that didn’t take off, twenty years in the past. That firm failed as a result of it was too carefully tethered to chipmaker Hitachi, Koike stated.
He hopes his second probability, Rapidus, will notice his dream of making a foundry that gives quick cycle time for patrons.
“My concept is single-wafer processing,” Koike stated. “It means the fab doesn’t have any inventory, so I can manufacture very exactly to regulate the cycle time.”

Koike goals to show the usual observe of processing a whole bunch of wafers at a time on its head. By extracting knowledge from a single wafer fairly than a whole bunch, Rapidus plans to chop cycle time by eliminating manufacturing issues quickly.
The corporate will even speed up output utilizing wafer bonding, a way that’s simply starting to win {industry} adoption.
“We are able to manufacture in a different way by attaching one wafer to a different to shorten cycle time,” Koike stated. “That’s form of a brand new concept.”
Rapidus will depend on assist from Japan’s CHIPS Act and an alliance with IBM to start out manufacturing of 2-nm chips by 2027. That’s after TSMC launches its 2-nm course of in 2025.
Rapidus is main Japan’s world partnership for R&D and mass manufacturing of next-gen semiconductors, in keeping with Satoshi Nohara, an official with Japan’s Ministry of Financial system, Commerce and Business (METI). Nohara is accountable for implementing the nation’s CHIPS Act.
Japan and the U.S. have been working to scale back dependence on China within the semiconductor provide chain, and Rapidus is an outgrowth of that partnership.
“The step to world partnership for R&D and mass manufacturing of next-generation semiconductors is a very powerful a part of our technique,” Nohara stated at a Might ITF World occasion held by Interuniversity Microelectronics Centre (imec) in Brussels. “The Rapidus, imec and IBM partnership is its first challenge.”
Imec is about to assist Rapidus develop constructing blocks essential for the mass manufacturing of 2-nm chips that can be utilized for 5G communications, quantum computing, knowledge facilities, autonomous automobiles and digital sensible cities.
$37 billion wanted to start
Rapidus might want to make investments about $37 billion to start out manufacturing, Koike stated. Neither he nor METI’s Nohara disclosed how a lot the Japanese authorities will present in subsidies.
TSMC’s new $8.6 billion chip fab in Japan will obtain a METI subsidy accounting for 40% of the price, in keeping with a Overseas Coverage article. Rapidus will get a subsidy from METI value about $2.5 billion, in keeping with a Reuters report.
Koike stated the monetary assist from the Japanese authorities will not be as beneficiant as different locations just like the U.S. and Europe which can be implementing their very own CHIPS Acts.
“Authorities assist for the semiconductor {industry} is robust,” Koike stated. “I believe in Japan, not so good.”
Main Japanese corporations like Sony, NTT Communications and a three way partnership created by Toyota and Denso will put money into Rapidus, Koike stated. He didn’t disclose the dimensions of the funding.
Rapidus plans to do meeting and check, together with heterogeneous integration, in its fab. That might additionally streamline cycle time.
“Japan has so many nice tools and supplies corporations for the backend,” Koike stated. “They’re prepared to hitch us.”
IBM affirmed its partnership with Rapidus.
“We’re assured that our work with Rapidus can be profitable and effectively applied,” Bethany McCarthy, an IBM spokesperson, instructed EE Occasions. “We lately welcomed the primary of many Rapidus researchers who’re becoming a member of us on-site at Albany NanoTech.”
IBM will assist Rapidus obtain its 2-nm goal, in keeping with Koike.
“That may be a key concern as a result of Japan’s logic know-how is 10 to fifteen years behind,” he stated.
Rapidus doesn’t plan to compete immediately with TSMC within the foundry enterprise, he added.
“We want to (goal) a particular fabrication marketplace for this know-how,” he stated, noting that focus areas embody high-performance computing and edge computing mixed with AI.
Koike’s eyes brighten on the point out of automotive chips.
“Automotive is likely one of the probabilities,” he stated. “Edge computing is doubtlessly one of many good alternatives.”
Analyst weighs possibilities of success
The possibilities of success for Rapidus are good given the prudent technique of the Japanese authorities, Paul Triolo, who advises world tech shoppers at Albright Stonebridge Group, stated in an unique interview with EE Occasions.
“Japan has taken one of many extra strategic and balanced approaches,” he stated. “They’re not attempting to leap and outcompete TSMC. They’re saying, ‘We wish to have these corporations to be gamers within the subsequent era of know-how.’”
The principle problem for Rapidus can be to commercialize IBM’s 2-nm know-how introduced in Might 2021, a world’s first by the corporate’s semiconductor analysis facility in Albany, New York.
“They need to work very carefully with IBM on this very sophisticated know-how that’s just a little bit off the principle roadmap,” Triolo stated.
It could possibly’t harm that Kasunari Ishimaru is among the many roughly 100 individuals on Koike’s crew.
Ishimaru was once the top of R&D at Kioxia, which Koike stated will even be a Rapidus associate. Ishimaru additionally had expertise working with IBM growing course of know-how from when he was with Toshiba.
“With Toshiba, I joined the IBM alliance to develop 32-nm-and-beyond know-how with high-Okay metallic gate,” Ishimaru instructed EE Occasions final month in Brussels.
