[0004][Field of Industrial Application] The present invention relates to a method for trimming a resistor of a thick film hybrid IC or the like. [0002] Generally, in thick film hybrid ICs, trimming is performed to bring the values of elements fabricated on a substrate, particularly resistance elements, within a predetermined range. This trimming is a method of increasing the resistance value by narrowing the width of the resistor or lengthening its effective length to obtain the desired value. [0003] As a conventional method for trimming a thick film resistor, there is laser trimming, in which, for example, a part of a resistor of a predetermined width is cut with a YAG laser or the like to narrow the width of the resistor and increase its resistance value. .

[0006][Problem to be Solved by the Invention] However, in this method of trimming a resistor, the resistance value of the resistor becomes higher than the target value due to laser irradiation failure, printing error, etc. In this case, the resistance value cannot be lowered again, and the resistor and even the hybrid I
All items up to C were defective. [0005] Therefore, an object of the present invention is to provide a method for trimming a resistor that can reduce its resistance value. [0006]

[0008][Means for Solving the Problems] The present invention provides RuO2-glass resistor paste with 0.00% Ag. This is a resistor trimming method in which a resistor containing 5 to 20% by weight is disposed on a substrate and the resistance value of the resistor is reduced by locally applying heat to the resistor. (0007] Here, Ag contained in the resistor is 0.5
If it is less than % by weight, the resistance value will not decrease. In addition, when Ag exceeds 20% by weight, Ag and RuO
There is no change in the resistance value even if the second pass is made and heated. [0008]

[0012]According to the method of trimming a resistor according to the present invention, the resistance value of the heated portion of the resistor decreases. This is because Ag becomes Ag in the RuCh-glass system due to high-temperature heating.
This is because this Ag- traps electrons. That is, this is because Ag-+e-→Ag. [0009] As a result, the resistance value of the high temperature heating portion will decrease. [00101] [Effect] According to the present invention, the resistance value of a resistor can be lowered, and a resistor caused by a trimming error or a printing error can be regenerated. Therefore, the yield can be improved. [00111] [Example] The following table shows the relationship between the Ag content and the change in resistance value.
