Gallium oxide and diamond are among the “emerging and core technologies” covered by the move.
The United States on Friday adopted new controls on technology exports that support the production of advanced semiconductors and gas turbine engines that it says are critical to its national security.
Gallium oxide and diamond are among the “emerging and core technologies” covered by the move because “devices that use these materials have significantly increased military potential,” the Commerce Department said.
“Technological advances that enable technologies such as semiconductors and motors to operate faster, more efficiently, longer and in worse conditions can be game-changers in both commercial and military contexts,” said Under Secretary of Commerce for Industry and Security Alan Estevez. “By recognizing the risks as well as the benefits and acting in concert with our international partners, we can ensure that our shared security goals are met.”
The four technologies are among the items agreed to be reviewed by the 42 participating countries at the December 2021 meetings. Export controls in the United States cover a wider range of technologies, including additional equipment, software and technologies used to manufacture semiconductors, than the international agreement.
Gallium oxide and diamond allow semiconductors to “operate under harsher conditions, such as higher voltages or higher temperatures. Devices that use these materials have greatly increased military potential,” Commerce said.
The checks include ECAD, a category of software tools used to verify integrated circuits or printed circuit boards “that can support many commercial and military applications including defense and communications satellites,” the department said.
In June 2021, the US-China Economic and Security Review Commission found that the department was not doing enough to keep sensitive technology out of the hands of the Chinese military. Delays in developing a list of emerging and essential technologies, as required by the 2018 law, could exacerbate national security risks, the report said.
