Scaling theory for double-gate SOI MOSFET's

Abstract

A scaling theory for double-gate SOI MOSFETs, which gives guidance for device design (silicon thickness t/sub si/; gate oxide thickness t/sub ox/) that maintains a subthreshold factor for a given gate length is discussed. According to the theory, a device can be designed with a gate length of less than 0.1 mu m while maintaining the ideal subthreshold factor. This is verified numerically with a two-dimensional device simulator.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
