A semiconductor structure includes a first dielectric layer, a first conductive via, a partial landing pad, a second dielectric layer, and a second conductive via. The first conductive via is disposed in the first dielectric layer. The partial landing pad is disposed on the first conductive via and the first dielectric layer, in which the partial landing pad has a top surface and a bottom surface, and the top surface of the partial landing pad has a width greater than or substantially equal to that of the bottom surface of the partial landing pad. The second dielectric layer is disposed on the partial landing pad. The second conductive via is disposed in the second dielectric layer and electrically connected to the partial landing pad.
