Abstract

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 includes: adjusting a parameter adjustable for a manufacturing device serving as a reference manufacturing device; obtaining a first shape of a pattern of a semiconductor device to be formed on a substrate; defining an adjustable parameter of another to-be-adjusted manufacturing; obtaining a second shape of the pattern formed on the substrate; calculating a difference amount between a reference finished shape and a to-be-adjusted finished shape; repeatedly calculating the difference amount by changing the to-be-adjusted parameter until the difference amount becomes equal to or less than a predetermined reference value; and outputting as a parameter of the to-be-adjusted manufacturing device the to-be-adjusted parameter.
