July 2022:
China’s top chip maker has likely gained the ability to produce 7-nanometre chips, according to a Canadian tech analysis firm, marking a significant breakthrough as the world’s second-largest economy pushes towards technological self-sufficiency to
to counter US sanctions.
March 2025:
The new bismuth-based transistor could revolutionize chip design, offering higher efficiency while bypassing silicon’s limitations.
Their newly developed 2D transistor is said to be 40% faster than the latest 3-nanometre silicon chips from Intel and TSMC while consuming 10% less energy. This innovation, they say, could allow China to bypass the challenges of silicon-based chipmaking entirely.
Led by physical chemistry professor Peng Hailin, the research team believes their approach represents a fundamental shift in semiconductor technology.
“If chip innovations based on existing materials are considered a ‘short cut,’ then our development of 2D material-based transistors is akin to ‘changing lanes,’” Peng said in the statement.
April 2026:
Chinese scientists say they have developed a wafer-scale 2D semiconductor growth method with 1,000 times faster growth, paving the way for industry advances.
The surging demand for high‑performance, low‑power chips driven by AI and large-language models has intensified the search for next‑generation semiconductor technologies.
Moore’s Law predicted a doubling of semiconductor capacity every two years but as chip dimensions continue to shrink, physical limitations make further performance scaling increasingly difficult.
AI rush turns everyday data storage into ‘digital gold’ for Hong Kong consumers
Two-dimensional (2D) semiconductors have emerged as a leading candidate for post‑Moore chip materials, as they could allow continued transistor scaling.
In a 2D semiconductor, its ability to conduct electricity can be altered by adding tiny amounts of other elements, a process called doping, which can result in n-type (negative) and p-type (positive) material
April 2026:
So irregardless of high end chip embargo to China, China is making do with pushing the envelope of low end chips, advancing in AI & other areas such as optoelectronics, where it can be used in LEDs, photodetectors and lasers.
