Abstract:
A decoupling capacitor cell includes: a first decoupling capacitor formed by only a pMOS transistor; and a second decoupling capacitor formed by two metal layers. The decoupling capacitor cell is arranged in an unused region not occupied by basic cells in a cell-based IC and is connected to a power wiring and a ground wiring.
