SMIC could have mastered the 7nm technology on its own without stealing anything from TSMC

Last month, it was discovered that the Chinese company SMIC had been supplying its customers for about a year with semiconductor components that were very close to the 7-nn TSMC products. In the face of sanctions and lack of access to advanced equipment, such production was extremely difficult, but the TSMC veteran stated that it was not the fact that it was a simple technology theft.

Interesting comments were made in an interview with the DigiTimes resource of former TSMC chief jurist Richard Turston, who is now one of the CEOs of SMIC, who transferred not only professional competencies but also some technological secrets to TSMC, but also to SMIC, but also to Samsung LSI, so China's contract chip manufacturer is not the only beneficiary of this expert's "work migration" with 35 years of industry experience.

This figure alone has not been limited to the case, and over time there are a lot of experts from TSMC in SMIC. Richard Turston has stressed that he does not have reliable information on SMIC's success in mastering technology or its analogies, but he knows how carefully TSMC protects the technology secrets associated with advanced lithography. The trials between SMIC and TSMC have been going on since 2003, and the TSMC's monitoring procedures have been very carefully developed. According to Turston, the professional qualities of Liang Mon Sun and the serious financial input of Chinese authorities into SMIC development have enabled companies to acquire more advanced technology than 14 n on their own, without improper borrowing of TSMC intellectual property.

It will be recalled that in July, independent researchers found that the chip designer ' s supply to MinerVa ' s minerVa chips of SMIC production was close to 7 nm TSMC products in terms of their structure and characteristics, given the Chinese company ' s lack of access to equipment that supports a lithography with super-hot lithographic radiation . It is believed that SMIC has made such progress in chip manufacturing technologies using only more primitive DUV scanners, but the U.S. authorities are currently considering banning their supply to China, so it is early to celebrate SMIC ' s victory.
