Patent ID: 8366434

Claim:
A set of lithography templates providing improved lithographic alignment comprising: a first template having an x,y grid such that a centermost point is arranged within a central region and has (x,y) coordinates (0,0), the first template includes an array of first geometries comprising N subfields arranged in J rows and K columns, wherein each column has a width ‘w’, and wherein each row has a height ‘h’; a second template having an array of second-layer geometries, each second geometry corresponding to a first geometry, wherein a centermost point of a second geometry is a spaced distance ‘w+Δw’ from a centermost point of an immediately laterally adjacent second geometry, and wherein a centermost point of a second geometry is a spaced distance ‘h+Δh’ from a centermost point of an immediately vertically adjacent second geometry, wherein Δw is not equal to zero, and wherein Δh is not equal to zero.
