IBM has announced a breakthrough in semiconductor technology with the development of a sub-1 nanometer chip, featuring a 0.7 nm transistor architecture. This achievement marks a significant milestone in the industry, as it demonstrates the possibility of continued scaling beyond traditional chip limits. The new chip technology, called nanostack, uses a three-dimensional design to pack nearly 100 billion transistors onto a chip the size of a fingernail. This innovation is expected to offer improved performance and energy efficiency, with potential applications in areas such as AI, cloud infrastructure, and next-generation electronic devices.
