摘要：
The present paper proposes an analytical model of threshold voltage and current voltage characteristics for short channel fully depleted cylindrical/surrounding gate MOSFET based on the solution of Poisson's equation in cylindrical coordinates. The analysis takes into account the field-dependent mobility, velocity saturation and the effect of source/drain resistance. Advantages of surrounding/cylindrical structure over the conventional planar structure are investigated in detail. The results so obtained are in good agreement with simulated data available in the literature. (C) 2001 Elsevier Science B.V. All rights reserved.
