Japan’s industry ministry has approved an additional 631.5 billion yen to accelerate research and development at the chipmaker Rapidus, according to a Reuters report. The funding is part of a national initiative to increase domestic production of advanced semiconductors and reinforce related supply chains.

Following this latest allocation, the total research and development assistance provided to Rapidus now stands at 2.354 trillion yen. The ministry also indicated that its subordinate organization, the New Energy and Industrial Technology Development Organization, will support semiconductor design projects involving Fujitsu and IBM Japan.

Rapidus is focused on developing next-generation logic semiconductors at the 2-nanometer scale, with an objective to begin mass production in the 2027 fiscal year. Earlier this year, the company secured approximately 160 billion yen in combined investment from private firms, alongside a planned 250 billion yen from government sources.
