Abstract
A novel technique for the real time monitoring of ion implant doses has been invented. This is the first real-time monitor to cover the high dosage range (10E13 to 10E16 ions/sq. cm.). The underlying principle of this new technique is the increase in the resistance of a metal silicide film after ion implantation. Measurement of this increase in a silicide film that has been included in a standard production wafer provides an index for correlation with the implanted ion dose.
