今天（10月2日），中国首条单晶纳米铜智能加工生产线在温州平阳投产。这标志着芯片制造关键材料——单晶纳米铜——实现国产化量产。单晶纳米铜，成品直径为13微米，约为头发丝十分之一细，是集成电路半导体封装的关键材料。
以往中国的半导体关键材料大部分来自进口，且原材料是贵金属金或者银，价格昂贵，成为制约中国芯片生产的“卡脖子”难题之一。
这次单晶纳米铜的技术突破，实现了用铜基新材料替代其他贵金属，大幅降低成本，价格较国外同类产品降低近五成。
这个原材料主要应用在通信、汽车领域以及医疗和工控领域的芯片上。目前平阳生产基地年产能为500万卷轴，达产后将满足国内相关行业约10%的使用需求，为中国集成电路“打破封锁、代替进口”的目标贡献力量。
China claims chipmaking breakthrough with mass production of key material just 1/10 width of a human hair

A smart assembly line for the manufacturing of nanometer mono-crystalline copper, the first of its kind in the country, became operational in Pingyang county in Wenzhou, East China’s Zhejiang Province on Saturday, according to Chinese state broadcaster, signaling that a key material in chipmaking has entered mass production locally.
The finished product of nanometer mono-crystalline copper, with a diameter of 13 micrometers, merely one-tenth of the width of a human hair, is a pivotal material used in semiconductor packaging. The country has previously relied on imports for the majority of key semiconductor materials, with raw materials – pricey precious metals such as gold and silver – becoming one of the neck-choking challenges for the country’s chipmaking, the state broadcaster reported.
The nanometer mono-crystalline copper breakthrough enables the replacement of other precious metals by new copper-based materials, substantially reducing the cost as the newly mass produced offering carries a price tag that’s nearly 50 percent lower than its peer products in overseas markets.
The raw material is mainly applied in chips used in telecommunications, vehicles, healthcare and industrial control.
Presently, the manufacturing base in Pingyang boasts an annual production capacity of 5 million reels. If running at full capacity, the base will be able to meet about 10 percent of the national need, thereby contributing to the country’s push for blockade breaking and import replacement in integrated circuits, the Saturday report said.
