Abstract :
It is shown that in MOS transistors, the traps in the oxide that interact with the semiconductor by the tunnelling of carriers, induce a transient on the drain current when the device is switched from accumulation to strong inversion. Their density can be extracted as in deep level transient spectroscopy
