Abstract:
In a method for producing a circuit-device, a method comprising the steps of:illuminating a first mask containing a process control mark to transfer the process control mark onto a predetermined area positioned in an exposure area on a substrate, said process control mark being comprised of a resolution chart to be used to check focus and/or exposure time;detecting the process control mark formed on the predetermined area, and then performing a predetermined process based on a detection result of the process control mark, said predetermined process including a focussing process and/or an exposure time control process;illuminating a second mask containing a circuit pattern to transfer the circuit pattern onto the exposure area on the substrate after the predetermined process is performed; andforming a bonding pad which is finally connected to an external wiring on the predetermined area after transferring the circuit pattern onto the substrate, so that the process control mark is at least partially covered by the bonding pad.
