Abstract

In order to realize a non cut trimming without damage to the resistor surface of thick film resistors for electronic devices, a microwave trimming method (MTM) has been developed. This trimming method having resistanceadjustments are due to peak power of microwave radiation and the number of pulse group. TCR and current noise of trimmed resistors are considerably improved by this trimming technique in the case of higher resistivity materials and worsen in the case of lower resistivity materials and there is no loss in power handling capacity of trimmed resistors.
