I am using this driver circuit to test IR2110/ IR2118 ICs

At low frequency everything is working fine. But when I am switching at high frequency(100kHz) IC is getting damaged. With increase in frequency, during turn on ringing is appearing in the voltage waveform ( I have connected a single resistor and mosfet to test the ICs).
My guess is IC damage is happening due to stray inductance of the breadboard and wire connectors. So it may work fine in the PCB.I want to know is anyone have worked on these kind of driver IC at 100kHz or above. Any suggestion and new ideas will be helpful.
