Abstract:
A resistor trimming method, comprising steps of:forming a first slit from an edge of a resistor formed between a pair of electrodes provided on an insulating substrate, said first slit being in the proximity of and parallel to a first one of said electrodes; forming a second slit as a continuation of said first slit toward a second one of said electrodes and perpendicular to said first slit; forming a third slit from an edge of said resistor in the proximity of and in parallel to the second of said electrodes; forming a fourth slit continuously from said third slit toward the first one of said electrodes and perpendicular to said third slit; forming at least one approximately L-shaped additional slit as a continuation of said first slit; and forming at least one approximately L-shaped further slit as a continuation of said third slit, said at least one additional slit and said at least one further slit alternate with one another.
