Abstract

PURPOSE:To reduce the resistance value of resistors at the time of trimming by arranging the resistors made of RuO2-glass resistor paste containing a specific amount of Ag on a substrate and locally heating the resistors. CONSTITUTION:Resistors made of RuO2-glass resistor paste containing 0.5-20wt.% Ag are arranged on a substrate and the resistors are locally heated so as to reduce the resistance value of the resistors at the time of trimming. When the Ag content in the resistors is <=0.5wt.%, the resistance value does not drop and, when the Ag content is >20%, paths are formed between the Ag and RuO2 and the resistance value does not change even when the resistors are heated. Therefore, the yield of the resistors can be improved, since defective products of the resistors produced by mistrimming or misprinting can be recycled.

[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. .

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.
