Abstract:
A method of forming a capacitor in a substrate having an integrated circuit so that the capacitor has a selected dielectric constant from a range of dielectric constants, comprising:forming in a substrate of a first material having a first dielectric constant a plurality of spaced conductive elements positioned close enough to one another to have a capacitance, a portion of the substrate being between the conductive elements, extending from at least one of the conductive elements to an adjacent one of the conductive elements;removing at least part of said portion of the substrate to define an empty space between the conductive elements; andplacing in said empty space an amount of a second material having a second dielectric constant, wherein the second dielectric constant is greater than the first dielectric constant, whereby the capacitance of the conductive elements after the step of placing said second material in said empty space is greater than the capacitance of the conductive elements prior to the step of removing.
