Abstract

An extensive network of N-channel transistor formed capacitor, with one node tie directly to V.sub.CC power bus and the other node directly V.sub.SS power bus, is implemented throughout all open space available on the whole silicon chip (memory as well as logic chip), particularly those directly underneath the metal power bus to achieve an on-chip power bus decoupling capacitor with capacitance in excess of 0.001 .mu.F.
