Abstract
A MOSFET model that is capable of handling the drain current above 10-10A within the temperature range of 220-340 K is proposed. The key feature of the model is that surface potentials at source and pinchoff points are used for the purpose of obtaining a smooth connection between the current solutions in the tail and the saturation regions. Comparison of the model with experiments has been carried out using n-channel MOSFET's with 7 × 1013, 7 × 1014, and 4 × 1015cm-3substrate impurity concentration and 675-, 1470-, and 5030-Å gate-oxide thickness. The theoretical calculations are in excellent agreement with the experimental measurements. It is shown that low-level current has a strong influence on the low-voltage static inverter circuit and dynamic memory.Keywords
