Patent ID: 7368207

Claim:
A method for dynamically registering multiple patterned layers on a substrate comprising: a) forming a first pattern on said substrate; b) forming a second pattern on said first pattern wherein said second pattern has associated image data, comprising providing said associated image data to an image data path which is in communication with a gating means and a cross-scan controller, wherein said image data path forms said second pattern by: i) obtaining expected feature location information for a first current region; ii) detecting the location of features in said first current region of said substrate having a first portion of said first pattern; iii) calculating an alignment correction signal from said detected location of the features of ii) and said expected location information in i); iv) applying said alignment correction signal to said gating means or said cross-scan controller in order to adjust the application of said associated image data in said first current region; and v) repeating steps i) and ii) until said second pattern is complete and is aligned with said first pattern.
