Patent ID: 7934175

Claim:
A parameter adjustment method for a plurality of manufacturing devices to form a pattern of a semiconductor device on a substrate using the manufacturing devices, the parameter adjustment method comprising: adjusting, by a computer, a parameter adjustable for a manufacturing device serving as a reference manufacturing device so as to fall within a range of a predetermined permissible variation and defining the adjusted parameter as a reference parameter of the reference manufacturing device; obtaining, by the computer, a first shape of a pattern of a semiconductor device to be formed on a substrate using the reference manufacturing device and a mask when the reference parameter is set for the reference manufacturing device and defining the obtained first shape as a reference finished shape; defining, by the computer, an adjustable parameter of another to-be-adjusted manufacturing device as a to-be-adjusted parameter of the to-be-adjusted manufacturing device; obtaining, by the computer, a second shape of the pattern formed on the substrate using the to-be-adjusted manufacturing device and the mask when the to-be-adjusted parameter is set for the to-be-adjusted manufacturing device and defining the obtained second shape as a to-be-adjusted finished shape; calculating, by the computer, a difference amount between the reference finished shape and the to-be-adjusted finished shape; comparing, by the computer, the calculated calculated with a predetermined reference value; outputting, by the computer, the to-be-adjusted parameter set for the to-be-adjusted manufacturing device as a parameter of the to-be-adjusted manufacturing device when the to-be-adjusted parameter resulting in the difference amount being equal to or less than the predetermined reference value; and repeatedly calculating, by the computer, the difference amount by changing the to-be-adjusted parameter until the difference amount becomes equal to or less than the predetermined reference value when the to-be-adjusted parameter resulting in the difference amount being more than the predetermined reference value and outputting, by the computer, as a parameter of the to-be-adjusted manufacturing device according to results obtained in the repeatedly calculating.
