Abstract
A trimming method for adjusting electrical characteristics of an adjustment circuit, which is provided in a semiconductor substrate, by cutting a fuse resistor provided in the semiconductor substrate. In a case where a cutting current flows to the fuse resistor to cut the fuse resistor, at least one of switching devices provided in the semiconductor substrate is set to a conductible state to make the cutting current flow to the switching device.
