| Abstract: | The synchronized movement process of the step and scan projection lithography was analyzed.The subsystems of the machine were divided into master synchronization subsystems and slave synchronization subsystems.The state broadcasting of master synchronization subsystems was realized by serial synchronization bus;the communication between subsystem and its data-collection system was analyzed and the communication was realized by using high speed serial hotlink.A synchronization experimental platform was established to validate the synchronization mechanism.The experimental results show the system is stable,reliable and satisfies with the requirements of synchronization and engineering. |
