Definition
The term, in context
AI-assisted draft · approved dataset
TSMC A16 is a chip manufacturing process node that combines gate-all-around nanosheet transistors with Super Power Rail, a backside power delivery scheme that routes power wiring beneath the transistor layer rather than above it, freeing front-side routing for signals and improving power delivery efficiency to the transistors.
