Abstract

A pattern generator includes: a writing tool and a calibration system. The writing tool is configured to generate a pattern on a workpiece arranged on a stage. The calibration system is configured to determine a correlation between a coordinate system of the writing tool and a coordinate system of a calibration plate on one of the stage and the workpiece. The calibration system is also configured to determine the correlation at least partly based on an optical correlation signal, or pattern, in a form of at least one optical beam being reflected from at least one reflective pattern on the surface of the calibration plate.

Description

[0001] related application [0002] This PCT patent application claims priority to Provisional US Patent Application no. 61 / 282,584, filed March 3, 2010. Background technique [0003] Pattern matching is useful in performing fast real-time alignment when forming a pattern on a workpiece. However, in at least some cases, it can be somewhat difficult to perform sufficiently accurate pattern matching and / or determine with sufficient accuracy the positions of pixels in the pattern to be generated on the workpiece. Contents of the invention [0004] Exemplary embodiments describe a pattern generator including a calibration system configured to determine a correlation between a coordinate system of a writing tool and a coordinate system of a calibration plate based at least in part on a light beam reflected from a calibration plate . [0005] According to at least some example embodiments, the calibration system is configured to determine, based at least in part on at least one ...
