Abstract:
A resistor comprising a resistor body of polycrystalline silicon and electric terminals arranged connected to the resistor body, the resistor body comprising a resistor portion between the electric terminals which gives the resistor its resistance, the polycrystalline silicon material in the resistor portion is doped with at least one dopant for achieving a desired resistance of the resistor, and the polycrystalline silicon material containing fluorine atoms for stabilizing the resistance, wherein the fluorine atoms in the polycrystalline silicon material in the resistor portion are provided in a concentration of at least 2.10.sup.19 cm.sup.-3 such that otherwise unsaturated bonds at grain boundaries in the polycrystalline silicon material are blocked to such a high extent that the resistance of the resistor portion is substantially constant in time.
