    摘要: Formation of a capacitor as part of an integrated circuit (IC) fabrication process is disclosed. The capacitor generally comprises a top conductive plate, a capacitor dielectric and a bottom conductive plate that respectively comprise a patterned layer of tantalum nitride TaN, a layer of a nitride based material and a layer of patterned polysilicon.

    摘要: As robust hinge post structure for use with torsional hinged devices such as micromirrors and method of manufacturing is disclosed. The fabrication process uses a protective layer such as BARC on the bottom of the aperture used to form the hinge post structure to protect an oxide layer during an etching step. The oxide layer, in turn protects the metal layer at the bottom of the aperture. Therefore, the metal layer, the oxide layer, and the protective layer prevent the erosion and/or pitting of the bottom electrode during a cleaning process, and provide additional support to the structure.
