Abstract:
1. A registration detection system, comprising: a first detection apparatus that is installed on the pathway to a collection in a transport container of substrates that are taken out of the transport container, after passing at least through an exposure process and a development process, performs registration detection in accordance with stipulated criteria of a resist pattern and a base pattern of said substrates after passing through said development process, and outputs results of said registration detection results for use in correction of said exposure process; a second detection apparatus situated outside of said pathway, and performing registration detection of the resist pattern and the base pattern of said substrates; and a criteria correction unit that compares the results of the registration detection performed by said first detection apparatus and the results of the registration detection performed by said second detection apparatus and performs correction on the criteria for the registration detection by said first detection apparatus based on the registration detection from said second detection apparatus.
