IBM has unveiled what it is calling the world's first 2-nanometer chipmaking technology, which will be smaller and faster than current leading-edge 5-nanometer processors, as well as the 3-nanometer chips that are expected to follow.

The company said the new chips could be up to 45% faster than the mainstream 7-nanometer chips used in many modern laptops and phones, and up to 75% more power-efficient.

IBM Research's Dario Gil said miniaturizing the chips' transistors boosts their speed and efficiency, while also creating problems with electron leakage when the switches are supposed to be off.

Gil said the IBM scientists draped sheets of insulating material just a few nanometers thick to stop leaks. The company said the 2-nanometer chips will take several years to come to market.
