    摘要: Method of fabricating a MIM capacitor and MIM capacitor. The method includes providing a substrate including a dielectric layer formed on a first conductive layer and a second conductive layer formed over the dielectric layer, and patterning a mask on the second conductive layer. Exposed portions of the second conductive layer are removed to form an upper plate of a MIM capacitor having edges substantially aligned with respective edges of the mask. The upper plate is undercut so that edges of the upper plate are located under the mask. Exposed portions of the dielectric layer and the first conductive layer are removed using the mask to form a capacitor dielectric layer and a lower plate of the MIM capacitor having edges substantially aligned with respective edges of the mask.

    摘要: The present invention provides a semiconductor structure including a buried resistor with improved control, in which the resistor is fabricated in a region of a semiconductor substrate beneath a well region that is also present in the substrate. In accordance with the present invention, the inventive structure includes a semiconductor substrate containing at least a well region; and a buried resistor located in a region of the semiconductor substrate that is beneath said well region. The present invention also provides a method of fabricating such a structure in which a deep ion implantation process is used to form the buried resistor and a shallower ion implantation process is used in forming the well region.

    摘要: A Metal Insulator-Metal (MIM) capacitor is formed on a semiconductor substrate with a base comprising a semiconductor substrate having a top surface and including regions formed in the surface selected from a Shallow Trench Isolation (STI) region and a doped well having exterior surfaces coplanar with the semiconductor substrate. An ancillary MIM capacitor plate is selected either a lower electrode formed on the STI region in the semiconductor substrate or a doped well formed in the top surface of the semiconductor substrate. A capacitor HiK dielectric layer is formed on or above the MIM capacitor lower plate. A second MIM capacitor plate is formed on the HiK dielectric layer above the MIM capacitor lower plate.

    摘要: A method and structure for reducing the corrosion of the copper seed layer during the fabrication process of a semiconductor structure. Before the structure (or the wafer containing the structure) exits the vacuum environment of the sputter tool, the structure is warmed up to a temperature above the water condensation temperature of the environment outside the sputter tool. As a result, water vapor would not condense on the structure when the structure exits the sputter tool, and therefore, corrosion of the seed layer by the water vapor is prevented. Alternatively, a protective layer resistant to water vapor can be formed on top of the seed layer before the structure exits the sputter tool environment. In yet another alternative embodiment, the seed layer can comprises a copper alloy (such as with aluminum) which grows a protective layer resistant to water vapor upon exposure to water vapor.
