  • Publication number: 20060273366
    Abstract: In a method of manufacturing a ferroelectric capacitor, a lower electrode layer is formed on a substrate. The lower electrode layer includes at least one lower electrode film. A ferroelectric layer is formed on the lower electrode layer, and then an upper electrode layer is formed on the ferroelectric layer. A hard mask structure is formed on the upper electrode layer. The hard mask structure includes a first hard mask and a second hard mask. An upper electrode, a ferroelectric layer pattern and a lower electrode are formed by partially etching the upper electrode layer, the ferroelectric layer and the lower electrode layer using the hard mask structure. The hard mask structure may prevent damage to the ferroelectric layer and may enlarge an effective area of the ferroelectric capacitor so that the ferroelectric capacitor may have enhanced electrical and ferroelectric characteristics.
