Patent ID: 7696603

Claim:
An integrated circuit back end capacitor structure comprising: (a) a first dielectric layer; (b) a bottom plate disposed on the first dielectric layer, the bottom plate being composed of thin film resistive material of a first layer of thin film resistive material; (c) a second dielectric layer disposed in contact with the bottom plate; (d) a middle plate composed of thin film material of a second layer of thin film material disposed on the second dielectric layer; (e) a third dielectric layer disposed in contact with the middle plate; (f) a top plate disposed in contact with the third dielectric layer, the top plate being composed of metal of a first metallization layer and contacting a contact area of the bottom plate through a corresponding via opening; and (g) an interconnect conductor composed of metal of the first metallization layer and disposed in contact with the third dielectric layer contacting a contact area of the middle plate through a corresponding via opening.
