    摘要: A method for fabricating an improved metal-insulator-metal capacitor is achieved. An insulating layer is provided overlying conducting lines on a semiconductor substrate. Via openings through the insulating layer to the conducting lines are filled with metal plugs. A first metal layer is deposited overlying the insulating layer and the metal plugs. A capacitor dielectric layer is deposited overlying the first metal layer wherein capacitor dielectric layer is deposited as a dual layer, each layer deposited within a separate chamber whereby pinholes are eliminated. A second metal layer and a barrier metal layer are deposited overlying the capacitor dielectric layer. The second metal layer and the barrier metal layer are patterned to form a top plate electrode. Thereafter, the capacitor dielectric layer and the first metal layer are patterned to form a bottom plate electrode completing fabrication of a metal-insulator-metal capacitor.

    摘要: The invention is a process for reducing variations in CD from wafer to wafer. It begins by increasing all line widths in the original pattern data file by a fixed amount that is sufficient to ensure that all lines will be wider than the lowest acceptable CD value. Using a reticle generated from this modified data file, the pattern is formed in photoresist and the resulting CD value is determined. If this turns out be outside (above) the acceptable CD range, the amount of deviation from the ideal CD value is determined and fed into suitable software that calculates the control parameters (usually time) for an ashing routine. After ashing, the lines will have been reduced in width by the amount necessary to obtain the correct CD. A fringe benefit of this trimming process is that edge roughness of the photoresist lines is reduced and line feet are removed.

    摘要: A plasma containing 5–10% oxygen and 90–95% of an inert gas strips photoresist from over a low-k dielectric material formed on or in a semiconductor device. The inert gas may be nitrogen, hydrogen, or a combination thereof, or it may include at least one of nitrogen, hydrogen, NH3, Ar, He, and CF4. The operating pressure of the plasma may range from 1 millitorr to 150 millitor. The plasma removes photoresist, the hard skin formed on photoresist during aggressive etch processes, and polymeric depositions formed during etch processes. The plasma strips photoresist at a rate sufficiently high for production use and does not appreciably attack carbon-containing low-k dielectric materials. An apparatus including a plasma tool containing a semiconductor substrate and the low oxygen-content plasma, is also provided.
