Abstract:
    This invention relates to a proces of manufacturing and adjusting a compound resistor. The compound resistor is formed of a resistive material forming a predominant portion of the resistance and having a small negative temperature coefficient (TCR) of resistance coupled with an adjustment material having an extremely low resistance and a very high positive TCR. After forming the resistive and adjustment portions, a portion of the adjustment material is removed to adjust the composite TCR of the compound resistor substantially to zero without significantly affecting resistance.
