Abstract
A novel thick film resistor configuration and a method for fabricating thick film resistors, by which such resistors can be processed to achieve targeted electrical properties in an as-fired condition. The configuration and method of this invention involve creating a thick film resistor in the form of a series of short resistors whose combined resistance values approximately equal the predetermined resistance value required of the thick film resistor by its hybrid electronic circuit, yet with the use of minimal post-firing trimming. Such a configuration and method enable the production of thick film resistors from the same ink composition but with significantly different aspect ratios, yet which exhibit minimal differences between TCR values. Consequently, thick film resistors configured and fabricated in accordance with this invention are characterized by enhanced production throughput, repeatability, and reliability.
