Abstract
In a stacked metal-oxide-semiconductor (SMOS) transistor, the transistor source, drain and channel each have a lower part formed in a silicon substrate and an upper part composed of recrystallized polysilicon. The device gate is located between the upper and lower channel parts. By vertically integrating a MOS transistor, performance limitations imposed by the direct scaling approach to device miniaturization are avoided.
