摘要:
A parallel plate capacitor formed in the back end of an integrated circuit employs conductive capacitor plates that are formed simultaneously with the other interconnects on that level of the back end (having the same material, thickness, etc). The capacitor plates are set into the interlevel dielectric using the same process as the other interconnects on that level of the back end (preferably dual damascene). Some versions of the capacitors have perforations in the plates and vertical conductive members connecting all plates of the same polarity, thereby increasing reliability, saving space and increasing the capacitive density compared with solid plates.
