SEMICONDUCTOR DEVICE HAVING DECOUPLING CAPACITOR FORMED ON CHIP SURFACE

摘要

PURPOSE: A semiconductor device is provided to compensate fluctuation or reduction of power supply voltage by forming a decoupling capacitor on a chip surface. CONSTITUTION: The device comprises a semiconductor chip; a plurality of pads arranged at an outside of the semiconductor chip to apply an external electric signal to an inside thereof; a plurality of a first and a second power lines alternatively arranged in the inside thereof, wherein each of the first and the second power lines is a path where a first and a second constant voltages are supplied; and at least one capacitor arranged on the semiconductor chip between a first and a second power lines.
