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 1):
A system for aligning a wafer, the system comprising a controller configured to:\n perform a coarse alignment procedure by:\n estimating a misalignment of the wafer based on a comparison of a plurality of electrical features on the wafer and a template, and \n adjusting the position of the wafer based on the estimated misalignment; and \n perform, after performing the coarse alignment procedure, a fine alignment procedure by:\n determining a center location of individual electrical features of the plurality of electrical features on the wafer, \n averaging the center locations of the individual electrical features together to obtain an average center location of the plurality of electrical features \n comparing the average center location with a reference location, and \n adjusting the position of the wafer based on the comparison if the average center location is not within a predetermined distance of the reference location.
