Abstract

This paper appraises the degree of agreement between simulated and experimental results of drain current versus drain voltage (I d - V d). It also derives the impact ionization rate formula inversely by compared the simulated and experimental dependence of the substrate current(Isub) on the gate voltage(V g). We found that: (1) for I d V d characteristics, the agreement in the linear region was off, but overall agreement was fairly good, and (2) the simulated I su b -C V g characteristics were in fairly good agreement with the experimental characteristics when the modified Keldish formula P ii = P 0((E - 1.12)/1.12)n with n of 7 and P 0 of 2.8 × 1011 s -1 was used as the formula for the impact ionization rate.
