Patent ID: 7974804

Claim:
A registration detection system, comprising: a first detection apparatus that is installed on a pathway to a collection in a transport container of substrates that are taken out of said transport container, after passing at least through an exposure process and a development process, and performs registration detection of a resist pattern and a base pattern of said substrates after passing through said development process, at multiple points of said substrates; a second detection apparatus situated outside of said pathway, and performing registration detection of the resist pattern and the base pattern of said substrates at more points of said substrates than said first detection apparatus; a generation unit that generates compensation data for said exposure process based on results of the registration detection performed by said first detection apparatus and results of the registration detection performed by said second detection apparatus, and a controller coupled to said first detection apparatus and said second detection apparatus; wherein said first detection apparatus comprises: a first optical device for forming optical images on said substrates; a first image capturing device for generating first image signals from said optical images; and a first image processing unit for processing said first image signals and calculating a first detection result; wherein said second detection apparatus comprises: a second optical device for forming optical images on said substrates; a second image capturing device for generating second image signals; and a second image processing unit for processing said second image signals and calculating a second detection result; and wherein said controller: generates a first-order component from said first detection result; generates a second-order component from said second detection result; and calculates correction data from said first-order component and said second order component.
