Abstract:
The present disclosure generally relates to a method for performing semiconductor device fabrication, and more particularly, to improvements in lithographic overlay techniques. The method for improved overlay includes depositing a material on a substrate, heating a substrate in a chamber using thermal energy, measuring a local stress pattern of each substrate, wherein measuring the local stress pattern measures an amount of change in a depth of the deposited material on the substrate, plotting a plurality of points on a k map to determine a local stress pattern of the substrate, adjusting the thermal energy applied to the points on the k map, determining a sensitivity value for each of the points on the k map, and applying a correction factor to the applied thermal energy to adjust the local stress pattern.

Claim (Index 8):
The method of  claim 7 , wherein the determining a sensitivity value in response to adjusting the thermal energy is determined for each of the plurality of points on the k map.
