  • Patent number: 6549643
    Abstract: A system and method for selecting key-frames to generate a content-based visual summary of video and facilitate digital video browsing and indexing, which provides a real-time approach for key-frame selection irrespective of the available computation power. A method for selecting key-frames according to one aspect of the present invention is based on quantifiable measures such as the amount of motion and behavior of curves defined statistically or non-statistically, i.e. by finding the monotonically increasing segments of a curve, instead of thresholding the statistically defined image dissimilarity measures.

  • Publication number: 20030025144
    Abstract: An integrated circuit device with high Q MIM capacitor and its forming process are disclosed. The MIM capacitor dielectric layer is formed of a material which has relatively high dielectric constant and can be used as an anti-reflection coating (ARC). In the process of patterning MIM capacitor electrodes, the MIM capacitor dielectric layer can be directly used as an anti-reflection layer. Therefore, there is no need to form an anti-reflection layer on the metal layer, and the complexity and the cost of forming process can decrease.

  • Patent number: 6426267
    Abstract: The present invention provides a method for fabricating a high-Q inductance device. First, a first dielectric layer is formed on a semiconductor substrate. A spiral conducting line is formed above the first dielectric layer. Then, a passivation layer is formed above the spiral conducting line and the first dielectric layer, such that a spiral air gap is formed in the passivation layer within the space around the spiral conducting line. Finally, the inductance device is immersed in an acid solution so as to increase the size of the spiral air gap.

  • Patent number: 6251788
    Abstract: A method for planarizing the surface of a semiconductor wafer is disclosed. It involves the steps of: (a) applying a coating solution containing a polymeric material on the dielectric film; (b) curing the polymeric material to cause the polymeric material to become hardened and form a polymeric layer; (c) subjecting the polymeric layer to a gas plasma treatment, so that at least a portion of the polymeric layer becomes a SiO2-like layer which can be polished by a conventional oxide-type CMP slurry; (d) depositing a PETEOS film on the SiO2-like layer; and (f) CMP polishing the PETEOS film and the SiO2-like laye using a conventional oxide-type CMP slurry. This method is particularly advantageous for fabricating semiconductor devices with relatively wide trenches wherein the polymer layer would warp into the bottom of the trench thus will not serve as an effective self-provided etch stop.
