  • Patent number: 7727777
    Abstract: In accordance with some embodiments, a ferroelectric polymer memory may be formed of a plurality of stacked layers. Each layer may be separated from the ensuing layer by a polyimide layer. The polyimide layer may provide reduced layer-to-layer coupling, and may improve planarization after the lower layer fabrication.
    Type: Grant

  • Publication number: 20070134818
    Abstract: According to one aspect of the invention, a method of constructing a memory array is provided. An insulating layer is formed on a semiconductor wafer. A first metal stack is then formed on the insulating layer and etched to form first metal lines. A polymeric layer is formed over the first metal lines and the insulating layer. A puddle of smoothing solvent is then allowed to stand on the wafer. The smoothing solvent is then removed. After the smoothing solvent is removed, the polymeric layer has a reduced surface roughness. A second metal stack is then formed on the polymeric layer and etched to form second metal lines.

  • Publication number: 20070003695
    Abstract: An embodiment of the invention is a method of manufacturing a polymer for a polymer ferroelectric memory. In particular, and among other features, the method of an embodiment alters the ferroelectric transition temperature, or Curie temperature, of the polymer by rapidly cooling the polymer from an elevated temperature. In particular, an embodiment increases the Curie temperature of the polymer, expanding the operating range of a polymer ferroelectric memory formed therewith.

  • Publication number: 20060183348
    Abstract: Multiple-layer films in integrated circuit processing may be formed by the phase segregation of a single composition formed above a semiconductor substrate. The composition is then induced to phase segregate into at least a first continuous phase and a second continuous phase. The composition may be formed of two or more components that phase segregate into different continuous layers. The composition may also be a single component that breaks down upon activation into two or more components that phase segregate into different continuous layers. Phase segregation may be used to form, for example, a sacrificial light absorbing material (SLAM) and a developer resistant skin, a dielectric layer and a hard mask, a photoresist and an anti-reflective coating (ARC), a stress buffer coating and a protective layer on a substrate package, and light interference layers.

  • Publication number: 20060057506
    Abstract: Photoresists may be formed over a structure that has been modified so as to poison a lower layer of the photoresist. Then, when the photoresist is patterned, it is only patterned down to the poisoned layer. The poisoned layer may be removed subsequently. However, because of the use of the modification process, the critical dimensions of the photoresist may be improved in some embodiments.
