    摘要: In a capacitor including a silicon substrate and an insulating layer formed on the silicon substrate having a contact hole, a lower electrode layer including a silicon diffusion preventing conductive layer and an oxidation resistance conductive layer, an upper electrode layer, and a high dielectric constant layer therebetween, the silicon diffusion preventing layer is located on or within the contact hole and is isolated from the high dielectric constant layer. The high dielectric constant layer is formed on an upper surface and a side surface of the oxidation resistance conductive layer.
