Abstract
A multilayer-type on-chip inductor with a conductive structure includes an insulating redistribution layer disposed on an inter-metal dielectric (IMD) layer, and first and second winding portions symmetrically arranged in the IMD layer and the insulating redistribution layer with respect to a symmetrical axis. The first and second winding portions each includes at least first and second semi-circular stacking layers arranged from the inside to the outside and in concentricity. The first and second semi-circular stacking layers each has a first trace layer in the insulating redistribution layer and a second trace layer in the IMD layer and correspondingly formed below the first trace layer. A first slit opening passes through the second trace layer and extends in the extending direction of the length of the second trace layer.
