華為仲有武器, 就係納米碳纖管, 雖然仲係研發階段, 一旦成功同專利到手, 現有矽既生產線全廢
最近聽到納米碳纖管有突破進展, 半導體革命來了

根據維基百科的介紹，碳納米管（英語：Carbon Nanotube，縮寫為CNT）是在1991年1月由日本筑波NEC實驗室的物理學家飯島澄男使用高分辨透射電子顯微鏡從電弧法生產的碳纖維中發現的。

Carbon nanotube computer refers to a computer built entirely using carbon nanotubes (CNT) based transistors. Researchers from Stanford University said that they had successfully built a carbon nanotube computer and their research paper published on 25 September 2013 in the journal Nature. They named their first carbon nanotube computer Cedric. It has a one-bit processor containing just 178 transistors.

In 2019, a team at the Massachusetts Institute of Technology created the 16-bit processor called RV16X-NANO. With 14 000 transistors (compared to only hundreds in the first CNT computer made in 2013) it is the largest computer chip yet to be made from carbon nanotubes. It was able to execute a "Hello, World!" program with a message: “Hello, world! I am RV16XNano, made from CNTs”.It is based on the RISC-V instruction set and runs standard 32-bit instructions on 16-bit data and addresses.

發現呢樣野, 同用咩技術去運用呢樣野係唔同嫁, 如果唔係點會有技術專利(eg: FinFET)

basically,  link included FYI
Carbon nanotube transistors are a step closer to commercial reality, now that MIT researchers have demonstrated that the devices can be made swiftly in commercial facilities, with the same equipment used to manufacture the silicon-based transistors that are the backbone of today’s computing industry.
