Abstract
In this paper, we studied the drain current in sub-micron MOS device in presence of hot carrier. The current relation is derived after solving the Poisson equation for surface potential. The effect of hot electrons on the drain current is analyzed in detail. The effect of hot carriers on the current can be minimized by choosing moderate substrate doping. The drain current decreases with increase in voltage which is developed at the boundary of the damaged region and non-damaged region (VP). The drain current is almost zero for larger damaged region irrespective of the sign of hot carrier charge density.
