Abstract: A diffused resistor for semiconductor integrated circuits which avoids the problems caused by the high surface current density. The resistor includes at least one semiconductor region of conductivity type opposite to the resistor proper located between a pair of ohmic contacts to the resistor region. This semiconductor region diverts the current flow from the surface of the resistor region and causes a more uniform current distribution across the surface of the ohmic contacts.
