Abstract
A passive device and method of fabricating the passive device are disclosed herein. The capacitor structure incorporates a resistor and a capacitor. An exemplary method includes receiving a substrate that has undergone front end of line (FEOL) processing, and performing back end of line (BEOL) processing on the substrate, wherein a capacitor structure is formed over the substrate during the BEOL processing, the capacitor structure incorporating a resistor with a capacitor. The BEOL processing can include performing a first metallization process to form a bottom plate of the capacitor structure; forming a dielectric spacer of the capacitor structure over the bottom plate; forming a top plate of the capacitor structure over the dielectric spacer; and performing a second metallization process to form contacts coupled to the top plate and the bottom plate of the capacitor structure.
