    摘要： Interconnect structures that include a passive element, such as a thin film resistor or a metal-insulator-metal (MIM) capacitor, methods for fabricating an interconnect structure that includes a passive element, and design structures embodied in a machine readable medium for designing, manufacturing, or testing an integrated circuit, such as a radiofrequency integrated circuit. A top surface of a dielectric layer is recessed relative to a top surface of a conductive feature in the dielectric layer. The passive element is formed on the recessed top surface of the dielectric layer and includes a layer of a conductive material that is coplanar with, or below, the top surface of the conductive feature.

    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.

    摘要： A method of forming a metal-insulator-metal (MIM) capacitor includes forming a first planar dielectric layer with a first metallization layer therein; forming a first passivation layer on top thereof; forming a planar conductive layer above the first passivation layer; patterning and selectively removing the conductive layer up to the first passivation layer in designated areas to form a set of conductive features; patterning and conformally coating the set of conductive features and the exposed first passivation layer with a high strength dielectric coating; disposing a second dielectric layer above the first passivation layer and enclosing the set of conductive features; patterning and selectively removing portions of the second substrate to form channels and trenches; performing a dual-Damascene process to form a second metallization layer in the trenches and channels and to form an upper conductive surface above the high strength dielectric coating.
