Abstract:
1. A method of manufacturing a semiconductor device, comprising: providing a substrate; forming a first conductive layer over a top surface of the substrate; forming a resistive layer over the substrate and the first conductive layer; forming a dielectric layer over the substrate, first conductive layer and resistive layer; forming a first passivation layer over the dielectric layer; removing first and second separate portions of the first passivation layer to expose first and second portions of the dielectric layer; forming a second conductive layer in direct contact with the first portion of the dielectric layer after forming the first passivation layer, wherein the dielectric layer, resistive layer, first conductive layer, and second conductive layer operate as a capacitor; etching a first opening in the second portion of the dielectric layer as defined by the removed second separate portion of the first passivation layer to expose a surface of the resistive layer; forming a third conductive layer over the second conductive layer and a portion of the first passivation layer; forming a fourth conductive layer over the third conductive layer; and forming a second passivation layer over the fourth conductive layer and first passivation layer.
