  • Patent number: 7916449
    Abstract: The method for forming the microelectronic device having at least one two or three dimensional capacitor includes creating, on a substrate, a plurality of components and a number of superimposed metal interconnection levels. An insulating layer is formed above a metal interconnection level, and a horizontal metal zone of a next metal interconnection level in which one or more of the insulating blocks created from this insulating layer are incorporated is formed therein. The zone is designed to form a lower structural part of the capacitor.

  • Patent number: 7911763
    Abstract: The present invention relates to a semiconductor device, and more particularly to a method for forming a metal/insulator/metal (MIM). The method comprises the steps of: forming a metal wiring surrounded by the inter-metal dielectric film; forming a plurality of insulating film on the metal wiring in sequence; and forming a metal barrier film on the insulating film, whereby the insulating film functioning as a buffer film can mitigate the stress between the films.

  • Patent number: 7907386
    Abstract: In a multilayer capacitor, widths of lead conductors of internal electrode and widths of lead conductors of internal electrode in an ESR control section are smaller than any one of widths of internal electrode and widths of internal electrode in a capacitance section. This narrows cross sections of the conductor portions connecting between the internal electrodes and the external electrodes, so as to her increase ESR. The widths of the respective lead conductors in the ESR control section are wider than widths of respective lead conductors in the capacitance section. This effectively prevents open failure and improves a yield of products.
