    Abstract: 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.

    Abstract: The invention is directed to unique high-surface area BEOL capacitor structures with high-k dielectric layers and methods for fabricating the same. These high-surface area BEOL capacitor structures may be used in analog and mixed signal applications. The capacitor is formed within a trench with pedestals within the trench to provide additional surface area. The top and bottom electrodes are created using damascene integration scheme. The dielectric layer is created as a multilayer dielectric film comprising for instance Al2O3, Al2O3/Ta2O5, Al2O3/Ta2O5/Al2O3 and the like. The dielectric layer may be deposited by methods like atomic layer deposition or chemical vapor deposition. The dielectric layer used in the capacitor may also be produced by anodic oxidation of a metallic precursor to yield a high dielectric constant oxide layer.

    Abstract: A method for forming a transmission line structure for a semiconductor device includes forming an interlevel dielectric layer over a first metallization level, removing a portion of the interlevel dielectric layer and forming a sacrificial material within one or more voids created by the removal of the portion of the interlevel dielectric layer. A signal transmission line is formed in a second metallization level formed over the interlevel dielectric layer, the signal transmission line being disposed over the sacrificial material. A portion of dielectric material included within the second metallization level is removed so as to expose the sacrificial material, wherein a portion of the sacrificial material is exposed through a plurality of access holes formed through the signal transmission line. The sacrificial material is removed so as to create an air gap beneath the signal transmission line.

    Abstract: Methods of fabricating a passive element and a semiconductor device including the passive element are disclosed including the use of a dummy passive element. A dummy passive element is a passive element or wire which is added to the chip layout to aid in planarization but is not used in the active circuit. One embodiment of the method includes forming the passive element and a dummy passive element adjacent to the passive element; forming a dielectric layer over the passive element and the dummy passive element, wherein the dielectric layer is substantially planar between the passive element and the dummy passive element; and forming in the dielectric layer an interconnect to the passive element through the dielectric layer and a dummy interconnect portion overlapping at least a portion of the dummy passive element. The methods eliminate the need for planarizing.
