Abstract:
Systems and methods that include providing for measuring a first topographical height of a substrate at a first coordinate on the substrate and measuring a second topographical height of the substrate at a second coordinate on the substrate are provided. The measured first and second topographical heights may be provided as a wafer map. An exposure process is then performed on the substrate using the wafer map. The exposure process can include using a first focal point when exposing the first coordinate on the substrate and using a second focal plane when exposing the second coordinate on the substrate. The first focal point is determined using the first topographical height and the second focal point is determined using the second topographical height.

Claim (Index 11):
A method for semiconductor device fabrication, comprising:\n providing a metrology tool embedded in a lithography tool; using the metrology tool to determine a plurality of topographical heights, wherein the using the metrology tool is a detector of air discharged onto a target surface; using a process parameter control module operable to generate a wafer map from the plurality of topographical heights, wherein the generating the wafer map includes:\n determining a comparison of each of the plurality of topographical heights with a predicted topographical height based on design data; \n sending the wafer map to the lithography tool operable to receive the wafer map; and \n performing an exposure process on the target surface using the lithography tool according to the wafer map, wherein the performing the exposure process includes exposing a first coordinate on the target surface to determine a first topographical height of the plurality of topographical heights and using the metrology tool to determine a second topographical height of the plurality of topographical heights, the first topographical height of a second coordinate on the target surface and the second topographical height of a third coordinate on the target surface.
