IBM Introduces the World’s First 2-nm Node Chip

IBM has become the first in the world to introduce a 2-nanometer (nm) node chip. IBM claims this new chip will improve performance by 45 percent using the same amount of power, or use 75 percent less energy while maintaining the same performance level, as today’s 7 nm-based chips. To give some sense of scale, with 2-nm technology, IBM could put 50 billion transistors onto a chip the size of a fingernail.

The foundation of the chip is nanosheet technology in which each transistor is made up of three stacked horizontal sheets of silicon, each only a few nanometers thick and completely surrounded by a gate.

The Nanosheet Transistor Is the Next (and Maybe Last) Step in Moore’s Law

    IBM Unveils World’s First 2 nm Chip

    IBM has unveiled the world’s first 2 nm chip, built at its R&D facility in Albany, New York. The test chip features gate-all-around transistors built with IBM’s nanosheet technology. Overall, IBM says the new process technology will enable 2 nm chips to achieve 45% higher performance or 75% lower power consumption than state-of-the art 7 nm chips in production today.

    IBM was also first to demonstrate 7 nm and 5 nm test chips. The test chip IBM showed today features about 50 billion transistors and uses nanosheet structures as part of a gate-all-around (GAA) transistor, the new transistor architecture heralded as the solution to the scaling limitations of its predecessor, the FinFET.

    FinFET was commercially introduced by Intel for the 22 nm node in 2011. GAA transistors replace FinFET’s fin with three wires, surrounded on all sides by the gate material. Surrounding the channel material like this allows better electrostatic control which in turn enables extremely small gate dimensions.

    IBM 2nm chip breakthrough claims more power with less energy

    IBM says it has made a significant breakthrough in computer processors by creating a 2nm chip in its test lab.

  3. impostor says:

    A breakthrough in IBM microprocessor technology, hopefully this step will bring about significant changes in the development of technology.

  4. Tomi Engdahl says:

    So IBM’s recent announcement regarding 2nm transistors isn’t just about scaling down “feature size” like the rest of the industry (TSMC, Intel) has been doing for the past decade.
    They’re ditching the FinFET technology altogether and going all-in on the new GAAT technology (Gate All-Around Transistor), aka Nanosheet, aka Nanowire.

    And since IBM no longer has a foundry to manufacture all this, they’ve partnered with Samsung and will use their fabs.

    Here’s an interesting explanation from Engadget

    The brilliant minds at #MIT teamed up with #TSMC to create a barrier-shattering breakthrough in chip fab technology that is truly bleeding-edge.

    TSMC And MIT Research Team Claims Amazing 1nm Chip Fab Breakthrough

    It was just earlier this month that IBM announced an incredible manufacturing breakthrough with its 2-nm manufacturing process that crammed 50 billion transistors into the size of a fingernail. While that’s still a future-looking technology that hasn’t made it into mass production (and thereby not a solution for our current chip shortage just yet), it’s already being surpassed. The combined research brainpower at the Massachusetts Institute of Technology (MIT) and Taiwan Semiconductor Manufacturing Company (TSMC) have announced some big breakthroughs using non-silicon materials to make very tiny transistors (as small as 1nm).

    The joint research paper, the abstract for which can be read on Nature’s website, describes manufacturing challenges caused by metal-induced gaps in conductivity while building the chips. Using the post-transition metal bismuth and some semi-conductive monolayer transition metal dichalcogenides, the gaps can be reduced in size, producing 2D transistors much smaller than had been previously possible.
