    摘要: An inductor structure (102) formed in an integrated circuit (100) is disclosed, and includes a first isolation layer (106) and a first core plate (104) disposed over or within the first isolation layer (106, 114). The first core plate (104) includes a plurality of electrically coupled conductive traces composed of a conductive ferromagnetic material layer. A second isolation layer (108) overlies the first isolation layer and an inductor coil (102) composed of a conductive material layer (118) is formed within the second isolation layer (108). Another core plate may be formed over the coil. The one or more core plates increase an inductance (L) of the inductor coil (102).

    摘要: The formation of a MIM (metal insulator metal) capacitor (164) and concurrent formation of a resistor (166) is disclosed. A copper diffusion barrier (124) is formed over a copper deposition (110) that serves as a bottom electrode (170) of the capacitor (164). The copper diffusion barrier (124) mitigates unwanted diffusion of copper from the copper deposition (110), and is formed via electro-less deposition such that little to none of the barrier material is deposited at locations other than over a top surface (125) of the deposition of copper/bottom electrode. Subsequently, layers of dielectric (150) and conductive (152) materials are applied to form a dielectric (172) and top electrode (174) of the MIM capacitor (164), respectively, where the layer of conductive top electrode material (152) also functions to concurrently develop the resistor (166) on the same chip as the capacitor (164).

    摘要: A method (10) of forming a MIM (metal insulator metal) capacitor is disclosed whereby adverse affects associated with copper diffusion are mitigated even as the capacitor is scaled down. A sidewall spacer (156) is formed against an edge (137) of a layer of bottom electrode/copper diffusion barrier material (136), an edge (151) of a layer of capacitor dielectric material (150) and at least some of an edge (153) of a layer of top electrode material. The sidewall spacer (156) is dielectric or non-conductive and mitigates “shorting” currents that can develop between the plates as a result of copper diffusion. Bottom electrode diffusion barrier material (136) mitigates copper diffusion and/or copper drift, thereby reducing the likelihood of premature device failure.
