Abstract:
In a semiconductor device and in methods of formation thereof, a semiconductor device comprises a substrate, a lower electrode on the substrate, and a dielectric layer on the lower electrode. An adhesion layer is positioned on the dielectric layer and an upper electrode is positioned on the adhesion layer. The adhesion layer contacts the dielectric layer and the upper electrode, and comprises a conductive material.
Abstract:
A semiconductor device includes a lower interconnection having second conductivity-type impurities on a substrate having first conductivity-type impurities. A switching device is on the lower interconnection. A first blocking layer is provided between the lower interconnection and the switching device. The first blocking layer includes carbon (C), germanium (Ge), or a combination thereof. A second blocking layer may be provided between the substrate and the lower interconnection.
