Publication number: 20070190760Abstract: 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.Type: ApplicationFiled: January 13, 2006Publication date: August 16, 2007Inventors: Douglas Coolbaugh, Hanyi Ding, Ebenezer Eshun, Michael Gordon, Zhong-Xiang He, Anthony Stamper

Publication number: 20070038968Abstract: Increase power line noise immunity in an IC is provided by using decoupling capacitor structure in an area of the IC that is typically not used for routing, but filled with unconnected and non-functional metal squares (fills). In one embodiment, a method includes providing a circuit design layout; determining a density of a structure in an area of the circuit design layout; and in response to the density being less than a pre-determined density for the structure in the area, filling in a portion of the area with at least one capacitor structure until a combined density of the structure and the at least one capacitor structure in the area is about equal to the pre-determined density. Power line noise immunity is increased by increasing decoupling capacitance without enlarging the IC's total size by using a (fill) area that would normally be filled with unconnected and non-functional metal shapes.Type: ApplicationFiled: August 10, 2005Publication date: February 15, 2007Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Florian Braun, Hanyi Ding, Kai Feng, Zhong-Xiang He, Howard Landis, Xuefeng Liu, Geoffrey Woodhouse
