VERFAHREN ZUM TRIMMEN DES WIDERSTANDSWERTES POLYKRISTALLINER SILICIUM- WIDERSTAENDE, INSBESONDERE FUER DIE VERWENDUNG ALS HALBLEITER IN INTEGRIERTEN SCHALTKREISEN

摘要

Current having a density higher than a critical value is passed through a polycrystalline resistor doped with impurities at a concentration higher than a critical value to decreasingly correct the initial value of the resistance, thereby trimming the resistance value of the resistor. When the resistor is used in a semiconductor integrated circuit, the current is passed through the existing (not additional) terminals of the integrated circuit.
