Abstract:
A method for creating a planar resistor on a substrate surface, comprising the steps of:depositing a insulator layer on the substrate surface; depositing a dielectric layer on the insulator layer; patterning the dielectric layer to create a resistor area; etching the patterned dielectric layer to form a dielectric resistor area, having a resistor length dimension, on the insulator layer; depositing a conductive layer on the insulator layer to abut the resistor length dimension of the dielectric resistor area to form the resistor length; planarizing the conductive layer and the dielectric resistor area to form a planar resistor area; depositing a resistive layer on the planar resistor area; patterning the resistive layer to create a resistor width dimension; and etching the resistive layer to form the resistor width.
