Zusammenfassung:A method for forming multiple resistors on a substrate. The method initially includes providing a first resistor on the substrate. A first dielectric layer is deposited, patterned, and selectively etched over the first resistor. Second resistor material is provided over the first dielectric layer. Furthermore, landing pad material is provided over the second resistor material. The landing pad material and the second resistor material are then selectively etched. The selective etching forms contacts for the first resistor in a first region, and forms a second resistor and associated contacts in a second region.
