ABSTRACT:
A resistor is formed by locally heating an insulating material layer between conductors to convert the heated material into a first resistor element. A second resistor element is formed to contact the first resistor element while measuring the resistance between the conductors, until a desired resistor composed of the first and second resistor elements and having a predetermined resistance value is obtained.
