Abstract:
A method for forming a capacitor structure comprising:providing a semiconductor substrate having a recess therein, the recess having a Periphery comprising a bottom and sidewalls; forming a first conductive-material-comprising layer over the semiconductor substrate, the first conductive-material-comprising layer lining the bottom and the sidewalls to partially fill the recess and extending laterally outward from the partially filled recess over an upper surface of the semiconductor substrate; filling the partially filled recess with an organic material, the filling forming an organic material layer over an upper surface of the first conductive-material-comprising layer; removing at least a portion of the organic material layer with a chemical mechanical polishing pad and an organic-material-removing fluid, wherein the organic-material-removing fluid is substantially unreactive with the first conductive-material-comprising layer and comprises less than or equal to 0.1 weight percent particles at an initiation of the removing; stopping the removing when substantially all of an upper surface of the first conductive-material-comprising layer is exposed forming a dielectric layer over the first conductive-material-comprising layer; and forming a second conductive-material-comprising layer over the dielectric layer.
