Employees move semiconductor testers on the assembly line of the Advantest Corp. plant in Ora, Japan on Aug. 10, 2012.
Japan's government on Friday said it plans to restrict exports of 23 types of semiconductor manufacturing equipment, aligning its technology trade controls with a U.S. push to curb China's ability to make advanced chips.
The trade and industry minister in a press release said it will impose export controls on six categories of equipment used in chip manufacturing, including cleaning, deposition, lithography and etching.
The export restrictions, which will come into force in July, are likely to affect equipment manufactured by a dozen Japanese companies, such as Nikon , Tokyo Electron , Screen Holdings and Advantest .
Washington, however, needs Japan and the Netherlands, which are key suppliers of such equipment, to join it to make those restrictions effective.
