    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: Method of fabricating a MIM capacitor and MIM capacitor. The method includes providing a substrate including a dielectric layer formed on a first conductive layer and a second conductive layer formed over the dielectric layer, and patterning a mask on the second conductive layer. Exposed portions of the second conductive layer are removed to form an upper plate of a MIM capacitor having edges substantially aligned with respective edges of the mask. The upper plate is undercut so that edges of the upper plate are located under the mask. Exposed portions of the dielectric layer and the first conductive layer are removed using the mask to form a capacitor dielectric layer and a lower plate of the MIM capacitor having edges substantially aligned with respective edges of the mask.

    摘要: Methods of forming a high dielectric constant dielectric layer are disclosed including providing a process chamber including a holder for supporting a substrate, introducing a first gas comprising a high dielectric constant (Hi-K) dielectric precursor and an oxygen (O2) oxidant into the process chamber to form a first portion of the high dielectric constant dielectric layer on the substrate, and switching from a flow of the first gas to a flow of a second gas comprising the Hi-K dielectric precursor and an ozone (O3) oxidant to form a second portion of the high dielectric constant dielectric layer on the first portion. In an alternative embodiment, another portion can be formed on the second portion using the oxygen oxidant. The invention increases throughput by at least 20% without reliability or leakage degradation and without the need for additional equipment.

    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.
