An IBM-led research team has demonstrated a fabrication process that makes semiconductor chips featuring 5-nm transistors.

Current state-of-the-art chips on the market have 10-nm transistors. An IBM team demonstrated 7-nm chips less than two years ago.

The research team constructed the chips with stacks of silicon nanosheets. The method is an alternative to the current FinFET three-dimensional transistor architecture for cramming circuitry onto chips. Semiconductor makers will continue to use FinFET when they begin manufacturing . . .
