20110279221 | RESISTOR AND METHOD OF FORMING A RESISTOR - A resistor and a method of forming a resistor are disclosed. The method of forming a resistor in accordance with an embodiment of the present invention can include: providing an electric conductor having a resistance area in which a plurality of through-holes are formed; measuring a resistance value of the resistance area; and compensating the resistance value of the resistance area by selectively removing a portion connecting the plurality of through-holes. Since it is possible to compensate the resistance value precisely by simply removing a portion connecting through-holes, the resistance value can be readily compensated. Moreover, since most of the through-holes needed for the adjustment of the resistance value can be formed by a common process, the production cost for forming a precise resistor can be saved. | 11-17-2011 |
