Abstract

A capacitor in an integrated circuit (“IC”) includes a core capacitor portion having first conductive elements electrically connected to and forming a part of a first node of the capacitor formed in a first layer and second conductive elements electrically connected to and forming a part of a second node of the capacitor formed in the first layer. The first and second conductive elements alternate in the first conductive layer. Third conductive elements electrically connected to and forming a part of the first node are formed in a second layer adjacent to the first layer. The capacitor also includes a shield capacitor portion having fourth conductive elements formed in at least first, second, third, and fourth layers. The shield capacitor portion is electrically connected to and forms a part of the second node of the capacitor and surrounds the first and third conductive elements.
