    摘要: A BEOL thin-film resistor adapted for flexible integration rests on a first layer of ILD. The thickness of the first layer of ILD and the resistor thickness combine to match the nominal design thickness of vias in the layer of concern. A second layer of ILD matches the resistor thickness and is planarized to the top surface of the resistor. A third layer of ILD has a thickness equal to the nominal value of the interconnections on this layer. Dual damascene interconnection apertures and apertures for making contact with the resistor are formed simultaneously, with the etch stop upper cap layer in the resistor protecting the resistive layer while the vias in the dual damascene apertures are formed.

    摘要: Ferro-electric capacitor modules, methods of manufacture and design structures. The method of manufacturing the ferro-electric capacitor includes forming a barrier layer on an insulator layer of a CMOS structure. The method further includes forming a top plate and a bottom plate over the barrier layer. The method further includes forming a ferro-electric material between the top plate and the bottom plate. The method further includes encapsulating the barrier layer, top plate, bottom plate and ferro-electric material with an encapsulating material. The method further includes forming contacts to the top plate and bottom plate, through the encapsulating material. At least the contact to the top plate and a contact to a diffusion of the CMOS structure are in electrical connection through a common wire.
