Advanced transistors (FinFET and GAA)

When standard cell height is expressed in the number of routing tracks, what is the effect of reducing the number of tracks?

  1. ACell area shrinks and density increases
  2. BCell area grows
  3. CThe number of wires increases
Show answer and explanation

Answer: A. Cell area shrinks and density increases

Standard cell height is expressed as the number of wires (tracks) that can pass over the cell. Fewer tracks means shorter cells, so the same circuit can be built in a smaller area. However, routing margin and the number of transistor fins decrease, so routing congestion and drive strength need attention.
