Abstract
A method for reducing single event upsets in an integrated circuit includes the step of providing a plurality of levels within the integrated circuit, wherein the plurality of levels within the integrated circuit are in a stacked arrangement. The method also includes the step of providing a plurality of metal fill patterns within each of the plurality of levels within the integrated circuit. The method further includes the step of placing the plurality of metal fill patterns within at least one of the plurality of levels in a pattern such that a line of sight towards an active silicon layer does not exist within the stacked arrangement of the plurality of levels, thereby increasingly absorbing ionizing radiation particles, and thereby reducing single event upsets in the integrated circuit.
