    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 layer of bottom electrode/copper diffusion barrier material (136) is formed (16) within an aperture (128) wherein the capacitor (100) is to be defined. The bottom electrode layer (136) is formed via a directional process so that a horizontal aspect (138) of the layer (136) is formed over a metal (110) at a bottom of the aperture (128) to a thickness (142) that is greater than a thickness (144) of a sidewall aspect (148) of the layer (136) formed upon sidewalls (132) of the aperture (128). Accordingly, the thinner sidewall aspects (148) are removed during an etching act (18) while some of the thicker horizontal aspect (138) remains. A layer of capacitor dielectric material (150) is then conformally formed (20) into the aperture 128 and over the horizontal aspect (138). A layer of top electrode material (152) is then conformally formed (22) over the layer of capacitor dielectric material (150) to complete the capacitor stack (154).
