    摘要: In the course of forming a resistor in the back end of an integrated circuit, an intermediate dielectric layer is deposited and a trench etched through it and into a lower dielectric layer by a controllable amount, so that the top of a resistor layer deposited in the trench is close in height to the top of the lower dielectric layer; the trench is filled and the resistor layer outside the trench is removed, after which a second dielectric layer is deposited. Vias passing through the second dielectric layer to contact the resistor then have the same depth as vias contacting metal interconnects in the lower dielectric layer. A tri-layer resistor structure is employed in which the resistive film is sandwiched between two protective layers that block diffusion between the resistor and BEOL ILD layers.

    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: A method to integrate MIM capacitors into conductive interconnect levels, with low cost impact, and high yield, reliability and performance than existing integration methods is provided. This is accomplished by recessing a prior level dielectric for MIM capacitor level alignment followed by deposition and patterning of the MIM capacitor films. Specifically, the method includes providing a substrate including a wiring level, the wiring level comprising at least one conductive interconnect formed in a dielectric layer; selectively removing a portion of the dielectric layer to recess the dielectric layer below an upper surface of the at least one conductive interconnect; forming a dielectric stack upon the at least one conductive interconnect and the recessed dielectric layer; and forming a metal-insulator-metal (MIM) capacitor on the dielectric stack. The MIM capacitor includes a bottom plate electrode, a dielectric and a top plate electrode. The bottom and top plate electrodes can comprise the same or different conductive metal.
