    Abstract: A method of fabricating a MIM capacitor is provided. 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.

    Abstract: 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.

    Abstract: Methods are disclosed for forming a varied impurity profile for a collector using scattered ions while simultaneously forming a subcollector. In one embodiment, the invention includes: providing a substrate; forming a mask layer on the substrate including a first opening having a first dimension; and substantially simultaneously forming through the first opening a first impurity region at a first depth in the substrate (subcollector) and a second impurity region at a second depth different than the first depth in the substrate. The breakdown voltage of a device can be controlled by the size of the first dimension, i.e., the distance of first opening to an active region of the device. Numerous different sized openings can be used to provide devices with different breakdown voltages using a single mask and single implant. A semiconductor device is also disclosed.
