India, June 25 -- International Business Machines Corp. (IBM) has unveiled the world's first sub-1 nanometer semiconductor technology, introducing a 0.7 nanometer (7 angstrom) chip featuring a new three-dimensional "nanostack" transistor architecture.
The breakthrough is designed to overcome the physical limits of traditional chip scaling and could pave the way for the next generation of artificial intelligence, cloud computing and advanced electronics.
The prototype packs nearly 100 billion transistors onto a chip the size of a fingernail, almost doubling the transistor density of IBM's 2 nm chip introduced in 2021. According to IBM, the new technology could deliver up to 50% higher performance or 70% greater energy efficiency than its 2...
