Patent ID: 7272460

Claim:
A computer implemented method for designing a manufacturing process of an electronic device, comprising: calibrating a technology computer-aided design system by fitting of simulation parameters of a manufacturing process simulation and an electrical characteristic simulation, the fitting performed by using a first feature of a first commercial manufacturing process of a first electronic device manufactured by first manufacturing facilities, and a first electrical characteristic of the first electronic device; acquiring a second feature of a trial manufacturing process of a second electronic device manufactured by second manufacturing facilities, and a second electrical characteristic of the second electronic device; calculating a simulation electrical characteristic of the second electronic device by substituting the second feature to a simulation manufacturing process of the manufacturing process simulation, the simulation manufacturing process corresponding to the trial manufacturing process; comparing the second electrical characteristic with the simulation electrical characteristic; creating a design specification of a second commercial manufacturing process of the second manufacturing facilities based on a difference between the second electrical characteristic and the simulation electrical characteristic; calculating another simulation electrical characteristic of the second electronic device by substituting a changed second feature to the simulation manufacturing process of the manufacturing process simulation using the technology computer-aided design system, when the trial manufacturing process includes a changed manufacturing process condition so as to be different from the first commercial manufacturing process, the changed second feature corresponding to the changed manufacturing process condition; and comparing the second electrical characteristic and the another simulation electrical characteristic and utilizing the comparison to verify the trial manufacturing process.
