Innosilicon, a Chinese company focusing on one-stop intellectual property (IP) and customized chip design, announced on Monday that it has completed the world’s first chip tape-out and test based on the FinFET N+1 advanced technology of Semiconductor Manufacturing International Corp (SMIC), the largest Chinese chipmaker.

A tape-out is the final phase of a design life cycle for a chip design before manufacturing starts.

All IP is developed in-house and the functions are tested once, Innosilicon said on its website. The firm invested tens of millions of yuan into optimizing chip design in 2019, when SMIC’s N+1 process was not that mature, according to Innosilicon.

N+1, SMIC’s next-generation foundry node, offers a conspicuous improvement in performance and logic density. Compared with its existing 14-nanometer (nm) process, N+1 manufacturing technology can increase a chip’s performance by 20 percent and cut its power consumption by 57 percent, said Liang Mengsong,

HONG KONG (Reuters) – Hong Kong-listed shares of Semiconductor Manufacturing International Corp fell more than 7% on Monday after the United States imposed restrictions on exports to China’s biggest chip maker, citing a risk of military use.

SMIC’s shares fell as much as 7.9% to HK$17.12 ($2.21), the lowest since May 29, and were last down 6.7%.

The company said it had not received any official notice of the restrictions and added it has no ties with the Chinese military.

Suppliers of certain equipment to SMIC will now have to apply for individual export licenses, according to a letter from the U.S. Commerce Department dated Friday and seen by Reuters.

Earlier this year SMIC raised $6.6 billion in a secondary listing on Shanghai’s tech-centric STAR market.
