Abstract: The invention is directed to a technique for reducing the time from the start of fabrication of a prototype structure to the completion of fabrication of a real structure. A device processing method includes steps of: fabricating a first structure using an ion beam under a first condition in a first region on a substrate; measuring a size of the first structure which is fabricated; comparing the measurement result with design data; determining a second condition from the comparison result; and fabricating a second structure using the ion beam under the second condition in a second region on the substrate.

Abstract: A customer's request is more appropriately reflected in the design. A method of processing a request for designing a device receives a required specification for a device from a user input and output device, searches a case similar to the required specification in the old case specification information, outputs the case similar to the required specification found in the old case specification information to the user input and output device, and calculates a specification of a design result of the device according to the required specification for an unauthorized input for the similar case from the user input and output device, or transmits a request for designing the device according to the required specification to an external design system, and outputs the design result of the device calculated or received from the design system to the user input and output device.
