Abstract
A spiral resistor being of a type formed on a semiconductor substrate to withstand high voltages, comprises at least one thin field-plate layer covering said substrate between adjacent turns of the resistor. This prevents the well-known phenomenon of the 'phantom gate' from occurring which would result in the characteristics of spiral resistors deteriorating over time.
