Abstract :
This paper discusses the device design of vertical surrounding gate (VSG) MOSFETs. Poisson´s equation is solved using a Laplace reduction technique and Bessel functions to predict the device characteristics. The concept of inverse natural/characteristic length (/spl gamma/) and critical length (L/sub critical/) is developed, which serves as a tool for device optimization for improved performance. Results thus obtained are in close proximity with published data available in the literature.
