    摘要： 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.

    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.
