The United States has quietly tightened export restrictions on chip equipment to China: 14nm and below are banned, or spread to TSMC

Bloomberg reported on July 30 that Lam Research and KLA, two U.S. chip equipment companies, have confirmed that the U.S. crackdown on Chinese chips has expanded from 10nm to 14nm, and the new regulations will affect the scope. It may not be limited to SMIC, but also includes other chip manufacturing companies investing and operating in China, such as TSMC in Taiwan. Wallace, Klei’s president and chief executive, said the company had received a notice from the U.S. Department of Commerce asking them not to supply China with equipment used in chip manufacturing at 14 nanometers and below.

In the past two weeks or so, all U.S. equipment makers have received letters from the U.S. Commerce Department asking them not to supply China with equipment used to make chips of 14 nanometers or less, according to people familiar with the matter. The remarks of Fanlin and Ke Lei are only the earliest disclosed concrete examples of the further suppression of China’s chip industry by the United States.

Bloomberg recently reported that the United States is pushing hard for allies such as the Netherlands and Japan to ban ASML and Nikon from selling to China the mainstream technology necessary to make most of the world’s chips. The new rules cover a wider range of semiconductors across many industries and are likely to affect many more companies than the usual restrictions on SMIC.

It is reported that the United States has previously prohibited the export of chip equipment of 10nm and below technology to SMIC without permission, but has not yet explicitly restricted the export of chip equipment of 14nm and below technology.

SpaceX: Working with the astronomy community to reduce the brightness of Starlink satellites

On July 31, SpaceX released a document titled “Brightness Mitigation Best Practices for Satellite Operators,” outlining its work with the astronomy community to reduce light pollution and reduce the brightness of Starlink satellites. SpaceX noted that by working together, it has identified and mitigated key causes of satellite brightness. The company is working to make the satellite “invisible to the naked eye” at its standard operating altitude.

According to reports, SpaceX has strengthened the mirror design on its Starlink satellites to avoid diffuse reflection of light. SpaceX also points out that not all materials are highly reflective, and some can absorb or make reflected light less bright. In addition, SpaceX has also used designs such as sun visors and radio frequency transparent mirror films to reduce the problem of sunlight scattering. In addition to this, SpaceX has also developed RF clear mirror films as an alternative to sun visors. The film scatters most of the sunlight away from the earth. SpaceX says it has been improving its mirror coatings to reduce the amount of light reflected back to Earth.

Compared to the first-generation satellites, SpaceX has also improved the support material between its batteries. Simply put, change the white material to a dark red material. The downside is that dimming the material increases the temperature of the solar array, which reduces performance. (IT House)

U.S. Department of Commerce: Will limit the scale of government subsidies to chip companies

According to a Reuters report on July 30, the U.S. Department of Commerce said it would limit the scale of government subsidies for semiconductor manufacturing, and would not allow companies to use funds to “bottom out.” The Commerce Department told local chip companies that subsidies would be “no more than the amount generated to ensure that projects operate within the United States,” adding that the department would prevent “competitive subsidies between states and localities.”
