Abstract:
A reticle used to make memory cells, said reticle comprising:at least one generally planar surface defining a plurality of lead line cutouts and a plurality of fill pattern cutouts therein, said plurality of fill pattern cutouts interspersed between said plurality lead line cutouts and spaced apart from each of said plurality of lead line cutouts by an amount sufficient to avoid capacitive communication between a metal lead line and a metal fill pattern formed on a memory cell by said reticle, wherein said plurality of lead line and fill pattern cutouts are disposed in an array within a surface of said reticle such that a substantially continuous straight-edged perifery around said array is defined by at least one of said lead line and fill pattern cutouts, and no portion of any of said fill pattern cutouts within said array extends laterally beyond said periphery; and a grid defined by at least a portion of said surface, said grid comprising an interconnected series of spaces between each adjacent said plurality of lead line and fill pattern cutouts such that a lateral distance defining the width of any one of said series of spaces is substantially equal to that of any other of said series of spaces within said grid, the longest linear dimension between each of said series of spaces is no longer than the longest dimension of any of said plurality of fill pattern cutouts and no intersection defined by a crossing between any two of said interconnected series of spaces includes uninterrupted linear dimensions.
