Fig. 1 shows the process of designing and manufacturing. Based on the specifications required by the customer 1, first the logic design 2 is performed, then the device layout design 3 is performed, and the artwork 4 is created based on this, and the mask 5 is created based on the artwork 4.
And a device is manufactured by the wafer process 6. After that, inspection 7 in the wafer state, assembly 8 to the mounted state, and inspection 9 in the mounted state are carried out. In this process, malfunction is usually found. The designer estimates the cause of the defect based on the inspection result and cuts the wiring etc. at the necessary places to confirm this (wiring disconnection 10) or connects by a method such as laser CVD or focused ion beam CVD. The cause of the defect is identified and confirmed by the debugging 12 such as (wiring connection 11) and then observing the operation state. After that, the logic design 2 and the layout design 3 are repeated again, and remanufactured and inspected. As a result, a new defect is revealed and the cause is estimated. Thereafter, this process is repeated to finally obtain the LSI 13 that performs a desired operation.

Perform inspection 5-9. Results of inspections 7 and 9 Debugging 12
When an error location is found by, the error location is sent to Japan 301 in the morning in the evening simultaneous country, the logic change is performed here, the result is sent to Europe 302 in the evening, the device design is changed, and so on. As a result, the cycle of logic design 2, device design 3, manufacturing 5, 6, 8 and inspection 7, 9 is 1
It can be shortened to / 3 period, and the development period can be greatly shortened.

In the second example, exactly the same steps are followed. In other words, in software development in Japan 301
Then, the concept design is carried out, and at the same time in the evening, the result is sent to Europe 302 in the morning, and detailed design is carried out in Europe 302. The results will be sent to the United States 303 in the morning at the same time in the evening, and the coding 17 will be performed. In addition, run 18 and debug are performed. If an error is found here, if there is a problem with the conceptual design due to the type of error, send it to Japan 301 and modify the conceptual design 22 here, and further modify the detailed design 16 in Europe 302. , Coding 17, Run 18, and Debugging in USA 303. If the type of error is a problem related to the detailed design, the detailed design 16 is sent to Europe 302 for correction, and sent to the United States 303 for coding 17 and debugging. As described above, the cycle of concept design 15, detailed design 16, coding 17, and debug can be shortened by utilizing the time difference between Japan, the US and Europe, and the development period can be greatly reduced.

In any of the above cases, in sending the result, data, drawings, programs, sentences, etc. are sent by computer communication, facsimile communication, etc. by a line including satellite communication 304, 305, 306, and telephone, video conference. Accurate information is exchanged by having a meeting with a system.

In the above example, Japan 301, Europe 30
2, the example of the United States 303 is given, but any point may be used if there is a necessary time difference. Also, the example of 3 points was given, but 2
