An intelligent assembly line for manufacturing nanoscale monocrystalline copper, the first of its kind in the country, became operational on Saturday in Pingyang County in Wenzhou, east China’s Zhejiang Province, according to the chain. Chinese state television, reporting that a key material in chipmaking has entered mass production locally.
The finished product of nanoscale single crystal copper, with a diameter of 13 microns – barely a tenth the width of a human hair, is an essential material used in semiconductor packaging. The country previously depended on imports for the majority of major semiconductor materials, with raw materials – expensive precious metals such as gold and silver – becoming one of the most difficult challenges for chipmaking. of the country, the state broadcaster reported.
The breakthrough of nanoscale monocrystalline copper allows replacement of other precious metals with new copper-based materials, significantly reducing costs, as the new mass-produced offering is priced almost 50% lower than its counterparts. in foreign markets.
The raw material is mainly used in chips used in telecommunications, vehicles, healthcare and industrial control.
Currently, Pingyang manufacturing base has an annual production capacity of 5 million coils. If operating at full capacity, the base will be able to meet about 10% of national needs, thus contributing to the country’s pressure to lift the blockade and replace imports of integrated circuits, according to Saturday’s report.
