Abstract:
A semiconductor device having internal power terminals including a positive power terminal supplying a high potential and a negative power terminal supplying a low potential to the internal device region of a semiconductor chip in which said positive power terminal and said negative power terminal are arranged uniformly in the internal device region of said semiconductor chip and power is supplied from the outside of said semiconductor chip to said internal power terminal,wherein a metalizing metal of the same layer as said internal power terminals is wired between said internal power terminals in a tandem shape so as to be connected to the internal power terminal of the same potential, a top and under layer connection VIA is provided in the position where said tandem metalizing metal wire and an under layer metalizing metal cross so as to supply power to the power wire of the internal device region made of said under layer metalizing metal, and only one metalizing metal layer of the same layer as a power source PAD supplying power from a package of the outside of said semiconductor chip to the internal device region of the semiconductor chip is used to lay the internal power wire between said power sources PAD, thereby supplying power to an internal device.
