IBM Just Shattered Moore's Law With Sub-1 Nanometer Chips
IBM today announced what it calls the world's first sub-1 nanometer chip technology, unveiling a new 0.7nm (7 angstrom) semiconductor process built around an entirely new transistor architecture dubbed "nanostack." The announcement is significant not only because it pushes semiconductor technology below the 1-nm threshold, but also because it demonstrates a potential path forward for chip scaling as traditional transistor miniaturization approaches its physical limits.
According to IBM, the new technology can pack nearly 100 billion transistors onto a chip roughly the size of a fingernail. It's nearly double the density of the company's prior 2nm research chip announced in 2021 and currently being commercialized by Rapidus in Japan. IBM projects the design could deliver up to 50% higher performance or 70% greater energy efficiency compared to its earlier 2nm technology.
Now, before anyone imagines transistors literally measuring less than a nanometer across, it's worth noting that modern process...
