Abstract
Deviation occurring in a particular region in a plane of a resistor group which constitutes a semiconductor integrated circuit is improved and a quick increase in yield is accomplished. Provided is a fuse trimming method for a semiconductor device in which circuit elements such as transistors and resistors are formed on a semiconductor wafer and which has fuse elements capable of adjusting a resistance value of the resistors by laser trimming, including a resistor correction step of correcting in the particular region of the semiconductor wafer the resistance value of the resistors based on an amount of deviation from a target value of the resistance value of the resistors.
