Abstract
Embodiments of the invention generally provide apparatus and methods of screen printing a pattern on a substrate. In one embodiment, a patterned layer is printed onto a surface of a substrate along with a plurality of alignment marks. The locations of the alignment marks are measured with respect to a feature of the substrate to determine the actual location of the patterned layer. The actual location is compared with the expected location to determine the positional error of the patterned layer placement on the substrate. This information is used to adjust the placement of a patterned layer onto subsequently processed substrates.
