Abstract:
A method of forming a resistor between two metallic circuit traces, which circuit traces have a volume resistivity less than about 5Ã—10âˆ’6 ohm-cm, and which circuit traces are upon and separated by an insulative substrate, which insulative substrate has a volume resistivity greater than about 1Ã—109 ohm-cm, which method comprises plating a resistive material, which resistive material has a volume resistivity of from about 500 to about 1Ã—10âˆ’4 ohm-cm, onto an area of the insulative substrate between the circuit traces, such that the resistive material connects the circuit traces and then trimming a portion of the resistive material from the insulative substrate such that the resistor has an insulation resistance equal to a predetermined amount of ohms.
