    摘要： Methods of forming a high dielectric constant dielectric layer are disclosed including providing a process chamber including a holder for supporting a substrate, introducing a first gas comprising a high dielectric constant (Hi-K) dielectric precursor and an oxygen (O2) oxidant into the process chamber to form a first portion of the high dielectric constant dielectric layer on the substrate, and switching from a flow of the first gas to a flow of a second gas comprising the Hi-K dielectric precursor and an ozone (O3) oxidant to form a second portion of the high dielectric constant dielectric layer on the first portion. In an alternative embodiment, another portion can be formed on the second portion using the oxygen oxidant. The invention increases throughput by at least 20% without reliability or leakage degradation and without the need for additional equipment.

    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： 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.

The via and upper line structure are filled with a planarizing layer, followed by forming and patterning a resist layer over the planarizing layer. An upper capacitor electrode structure is defined in the upper ILD layer corresponding to a removed portion of the resist. The via, upper line structure and upper capacitor electrode structure are filled with conductive material, wherein a MIM capacitor is defined by the lower capacitor electrode, first dielectric capping layer and upper capacitor electrode structure.
