ABSTRACT:
A trimming resistor element includes a high-resistance film of high resistivity formed on an insulation film on the main surface of a substrate, and a low-resistance region which is formed by selectively subjecting the high-resistance film to a predetermined process so as to lower the resistivity thereof. A resultant resistance of the low-resistance region and the high-resistance film can be adjusted by selectively cutting off part of the low-resistance region.
