<p><P>PROBLEM TO BE SOLVED: To provide a capacitor anode that is formed from ceramic particles (e.g., Nb<SB>2</SB>O<SB>5</SB>, Ta<SB>2</SB>O<SB>5</SB>) capable of being chemically reduced to form an electrically conductive composition (e.g., NbO, Ta). <P>SOLUTION: For instance, a slip composition containing the ceramic particles may be initially formed and deposited onto a carrier substrate in the form of a thin layer. If desired, multiple layers may be formed to achieve the target thickness for the anode. Once formed, the layer(s) are subjected to a heat treatment to chemically reduce the ceramic particles and form the electrically conductive anode. Contrary to conventional press-formed anodes, the slip-formed anodes of the present invention may exhibit a small thickness, high aspect ratio, and uniform density, which may lead to an improved volumetric efficiency and equivalent series resistance (ESR). <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
