原标题：台积电 2nm 预计 2025 年量产，业界看好其领先三星和英特尔9 月 12 日消息，据台媒《经济日报》报道，晶圆代工厂台积电 2nm 制程将于 2025 年量产，市场看好进度可望领先对手三星及英特尔。台积电先进制程进展顺利，3nm 将在今年下半年量产，升级版 3nm（N3E）制程将于 3nm 量产一年后量产，即 2023 年量产，2nm 预计于 2025 年量产。台积电 2nm 厂将落地竹科宝山二期扩建计划，“竹科管理局”已展开公共设施建设，台积电 2nm 厂也开始进行整地作业。

二 |     LOS ANGELES -- A U.S. Navy sailor charged with providing sensitive military information to China pleaded guilty in Los Angeles on Tuesday to conspiring with a foreign intelligence officer and receiving a bribe, federal prosecutors said. Petty Officer Wenheng Zhao, 26, originally pleaded not guilty when he was charged Aug. 4. The Justice Department alleges that Zhao, based at Naval Base Ventura County, north of Los Angeles, conspired to collect nearly $15,000 in bribes from a Chinese intelligence officer in exchange for information, photos and videos of involving Navy exercises, operations and facilities.The information included plans for a large-scale U.S. military exercise in the Indo-Pacific region, which detailed the location and timing of naval force movements, prosecutors said. The Chinese officer told Zhao the information was needed for maritime economic research to inform investment decisions, according to the indictment.Zhao, who also went by the name Thomas Zhao and held a U.S. security clearance, “admitted he engaged in a corrupt scheme to collect and transmit sensitive U.S. military information to the intelligence officer in violation of his official duties,” the U.S. Attorney's Office said in a news release Tuesday. Zhao, of Monterey Park, California, faces a statutory maximum penalty of 20 years in federal prison. He has been in custody since his arrest on Aug. 3.Zhao was charged on the same day as another California-based Navy sailor who is accused of similar crimes. But they are separate cases, and federal officials haven't said if the two were courted or paid by the same Chinese intelligence officer as part of a larger scheme. Jinchao Wei, a 22-year-old assigned to the San Diego-based USS Essex, is charged with providing detailed information on the weapons systems and aircraft aboard the Essex and other amphibious assault ships that act as small aircraft carriers. He pleaded not guilty in federal court in San Diego. Last week, a former U.S. Army intelligence officer was charged in Seattle with attempting to provide classified defense information to the Chinese security services during the outbreak of the COVID-19 pandemic. Sgt. Joseph Daniel Schmidt, 29, was arrested Oct. 6 at San Francisco International Airport as he arrived from Hong Kong, where he had been living since March 2020, the Justice Department said. A federal grand jury returned an indictment charging him with retention and attempted delivery of national defense information. U.S. District Court records in Seattle did not yet list an attorney representing Schmidt on the charges, and neither the U.S. attorney’s office nor the federal public defender’s office had information about whether he had a lawyer.An FBI declaration filed in the case quoted Schmidt as telling his sister in an email that he left the U.S. because he disagreed with unspecified aspects of American policy.。

三 | 台积电 2nm 首次采用纳米片架构，相较 N3E 制程，在相同功耗下频率可提升 10% 至 15%。在相同频率下，功耗降低 25% 至 30%。台积电总裁魏哲家日前在技术论坛中强调，台积电 2nm 将会是密度最优、效能最好的技术。市场也看好，台积电 2nm 进度将领先对手三星及英特尔。IT之家了解到，此前消息称，虽然在 3nm 世代略有保守，但无论如何，鳍片 (Fin) 宽度都已经接近实际极限，再向下就会遇到瓶颈，所以外资法人预估台积电 2nm 先进制程将采用环绕式闸极场效电晶体 GAAFET 高端架构生产 2nm 芯片。返回搜狐，查看更多责任编辑：
