  • Publication number: 20060220080
    Abstract: An embodiment mitigates one or more of the limiting factors of fabricating polymer ferroelectric memory devices. For example, an embodiment reduces the degradation of the ferroelectric polymer due to the polymer's reaction with, and migration or diffusion of, adjacent metal electrode material. Further, the ferroelectric polymer is exposed to fewer potentially high temperature or high energy processes that may damage the polymer. An embodiment further incorporates an immobilized catalyst to improve the adhesion between adjacent layers, and particularly between the electrolessly plated electrodes and the ferroelectric polymer.

  • Publication number: 20060157764
    Abstract: Embodiments of the invention provide a method for producing ferroelectric polymer devices (FPMDs) employing conditions that avoid or reduce detrimental impact on the ferroelectric polymer film. For one embodiment, a damascene patterning metallization technique is used. For one embodiment a first metal layer is deposited on a substrate to form the bottom electrode for the FPMD. The first metal layer is capped with a selectively deposited diffusion barrier. A layer of ferroelectric polymer film is then deposited on the first conductive layer. The ferroelectric polymer film is planarized. A second metal layer is deposited on the ferroelectric polymer film layer to form the top electrode of the FPMD. The second metal layer is deposited such that the ferroelectric polymer film is not substantially degraded. For various alternative embodiments the various component processes may be accomplished at temperatures far below those employed in a conventional damascene patterning metallization process.

  • Patent number: 7009272
    Abstract: A series of conductive layers separated by interlayer gaps is formed adjacent a substrate layer, the conductive layer and interlayer gap dimensions defining aspect ratios for trenches between the conductive layers. A layer of dielectric material is deposited over the conductive layers using plasma enhanced chemical vapor deposition. Trenches having aspect ratios within specified geometric categories are incompletely filled, leaving interlayer voids which may have desirable dielectric properties.

  • Patent number: 7001782
    Abstract: Some embodiments for a method to fill interlayer vias with a suitable metal in a ferroelectric polymer memory die to reduce the step height and improve the thermal and electrical properties of the via. The method uses an electroless plating method to fill the vias, which is compatible with the ferroelectric polymer memory die processing temperature limits. The resulting process produces via fill metal plugs in the ferroelectric memory die, which allows for the deposition of a thin metal layer over the vias, while at the same time improving the electrical and thermal properties of the vias. Other embodiments are described and claimed herein.

  • Patent number: 6951506
    Abstract: The present invention describes a method for creating a differential polish rate across a semiconductor wafer. The profile or topography of the semiconductor wafer is determined by locating the high points and low points of the wafer profile. The groove pattern of a polish pad is then adjusted to optimize the polish rate with respect to the particular wafer profile. By increasing the groove depth, width, and/or density of the groove pattern of the polish pad the polish rate may be increased in the areas that correspond to the high points of the wafer profile. By decreasing the groove depth, width, and/or density of the groove pattern of the polish pad the polish rate may be decreased in the areas that correspond to the low points of the wafer profile. A combination of these effects may be desirable in order to stabilize the polish rate across the wafer surface in order to improve the planarization of the polishing process.
