Abstract:
Various embodiments of aligning wafers are described herein. In one embodiment, a photolithography system aligns a wafer by averaging individual via locations. In particular, some embodiments of the present technology determine the center locations of individual vias on a wafer and average them together to obtain an average center location of the set of vias. Based on a comparison of the average center location to a desired center location, the present technology adjusts the wafer position. Additionally, in some embodiments, the present technology compares wafer via patterns to a template and adjusts the position of the wafer based on the comparison.

Claim (Index 12):
A system for aligning a wafer, the system comprising a controller configured to:\n determine center locations of individual electrical features of a plurality of electrical features on a wafer; average the center locations of the individual electrical features together to obtain an average center location of the plurality of electrical features; compare the average center location with a reference location; and adjust the position of the wafer based on the comparison if the average center location is not within a prescribed distance of the reference location.
