PROBLEM TO BE SOLVED: To suppress a power supply noise with a small chip area of a CMOS LSI maintained. SOLUTION: A semiconductor device having a CMOS primitive cell comprises an element layer including the CMOS primitive cell, and an interconnection layer provided on the element layer. The interconnection layer comprises a first power supply wiring 40 connected to the CMOS primitive cell and having a first power supply potential VDD, and a first ground wiring 50 connected to the CMOS primitive cell and having a first ground potential GND. The element layer comprises a first decoupling capacitor DC3 provided beneath the wiring 40, and a second decoupling capacitor DC4 provided beneath the wiring 50. COPYRIGHT: (C)2007,JPO&INPIT
