Abstract:
1. A semiconductor device comprising: a substrate coated with an insulating layer; a connecting part connected to a conductive layer through the insulating layer of the substrate, the connecting part having an upper surface; a seed separating layer formed around the connecting part and the insulating layer, the seed separating layer defining an open region that exposes at least part of the connecting part, the seed separating layer having an upper surface disposed above the upper surface of the connecting part; a seed layer disposed in and filling the open region of the seed separating layer and covering a first portion of the seed separating layer, the seed layer having an upper surface disposed above the upper surface of the seed separating layer and a lower surface that engages connecting part and that is disposed below the upper surface of the seed separating layer; a capacitor comprising a lower electrode formed on the seed layer, a dielectric medium formed on the lower electrode and further covering a second portion of the seed separating layer, and an upper electrode formed on the dielectric medium; and wherein the seed layer is disposed between the connecting part and the dielectric medium of the capacitor.
