<p>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.</p> |
