Abstract:
The present disclosure generally relates to semiconductor structures and, more particularly, to mask structures and methods of manufacture. The method includes determining a plane through a frontside surface and a backside surface of a mask, each plane representing a flatness of the frontside surface and the backside surface, respectively; subtracting, using at least one computing device, a difference between the plane of the frontside surface and the plane of the backside surface to find a thickness variation; generating, using the at least one computing device, a fitting to fit the thickness variation; and subtracting, using the at least one computing device, the fitting from the thickness variation to generate a residual structure for collecting a residual flatness measurement.

Claim (Index 19):
A system for analyzing blank flatness, comprising:\n a CPU, a computer readable memory and a computer readable storage media; first program instructions to find a thickness variation of a structure by subtracting a flatness between a frontside surface and a backside surface of the structure; second program instructions to fit the thickness variation with a polynomial fit; third program instructions to generate a residual structure by subtracting the polynomial fit from the thickness variation; and fourth program instructions to find a residual flatness measurement by taking a difference between the highest point and the lowest point present in the residual structure, wherein\n the first, second, third and fourth program instructions are stored on the computer readable storage media for execution by the CPU via the computer readable memory.
