ABSTRACT:
A resistor and a structure for changing an electrical resistance of a resistor. Initially, the resistor is provided, wherein the resistor has a length L and an electrical resistance R1. A portion of the resistor is exposed to a laser radiation, wherein the portion includes a fraction F of the length L of the resistor. After the resistor has been exposed to the laser radiation, the resistor has an electrical resistance R2, wherein R2is unequal to R1.
