What is a gate-all-around (nanosheet) transistor?
A gate-all-around (GAA) transistor surrounds its channel with the gate on all sides, typically using stacked horizontal silicon sheets called nanosheets. It succeeds the FinFET design to give better control of current at very small dimensions.
Why it matters for investors
The switch to GAA changes which manufacturing steps are hardest, with more emphasis on deposition, etching and selective removal of material. That can shift equipment spending between toolmakers.
Each leading-edge manufacturer has announced its own GAA node and timing. Execution on these transitions affects their ability to win customers for advanced chips.
