Abstract:
The effect of plasma damage on the MOSFET's flicker noise properties is examined in this work. We observe an abnormal noise peak in the 1/f noise spectrum at around 2 kHz which is a characteristic of the plasma damage. The dependence of the noise peak on the plasma induced degradation was studied in virgin n- and p-channel MOSFETs and this peak is shown to correlate well with the amount of damage in the p-MOSFETs.
