Disclosed is a wafer-scale chip structure including a semiconductor wafer and multiple dies on the semiconductor wafer. The dies can include at least two dies with different patterns of fill shapes. Also disclosed are wafer-scale chip design methods and systems. In the design methods and systems, post-chip layout wafer-level topography optimization is performed to, for example, minimize performance variations between dies of the same design within the wafer-scale chip. Specifically, across-wafer die placement and wafer-level topography information is used to custom design and/or select different patterns of fill shapes to be inserted into the layouts of dies placed at different locations across the wafer-scale chip (including different patterns to be inserted into the layouts of dies that have the same design) in order to generate a design that minimizes either all across-wafer thickness variations or at least across-wafer thickness variations associated with specific dies having the same specific design.
