THIS IS A SUPPLEMENTAL REPORT FOR MFR REPORT #8010047-2014-00650 TO PROVIDE DEVICE EVALUATION RESULTS. OLYMPUS PERFORMED FURTHER INVESTIGATION FOR THE CAUSE OF THE FET (FIELD EFFECT TRANSISTOR) DAMAGE AND THE DAMAGED FET HAD EXCESSIVE CURRENT LEAKAGE. THE AMOUNT OF THE LEAKAGE CURRENT DEPENDS ON THE ELECTRICAL CHARACTERISTIC VARIABILITY OF THE FET. OLYMPUS IMPLEMENTED A COUNTERMEASURE FOR THIS PHENOMENON TO REDUCE THE ELECTRICAL CHARACTERISTIC VARIABILITY OF THE FET.
