    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 method of forming a metal-insulator-metal (MIM) capacitor includes forming a first planar dielectric layer with a first metallization layer therein; forming a first passivation layer on top thereof; forming a planar conductive layer above the first passivation layer; patterning and selectively removing the conductive layer up to the first passivation layer in designated areas to form a set of conductive features; patterning and conformally coating the set of conductive features and the exposed first passivation layer with a high strength dielectric coating; disposing a second dielectric layer above the first passivation layer and enclosing the set of conductive features; patterning and selectively removing portions of the second substrate to form channels and trenches; performing a dual-Damascene process to form a second metallization layer in the trenches and channels and to form an upper conductive surface above the high strength dielectric coating.

    摘要： A polysilicon containing resistor includes: (1) a p dopant selected from the group consisting of boron and boron difluoride; and (2) an n dopant selected from the group consisting of arsenic and phosphorus. Each of the p dopant and the n dopant has a dopant concentration from about 1e18 to about 1e21 dopant atoms per cubic centimeter. A method for forming the polysilicon resistor uses corresponding implant doses from about 1e14 to about 1e16 dopant ions per square centimeter. The p dopant and the n dopant may be provided simultaneously or sequentially. The method provides certain polysilicon resistors with a sheet resistance percentage standard deviation of less than about 1.5%, for a polysilicon resistor having a sheet resistance from about 100 to about 5000 ohms per square.
