摘要

为了克服悬浮体效应引起的劣化和抑制薄膜绝缘子上硅(SOI) mosfet中寄生源极/漏极电阻的增加,提出了一种凹型SOI- mosfet (COSMOS)。该结构实现了部分薄膜SOI区域用作完全耗尽通道,厚膜SOI区域用作源/漏极。COSMOS的独特之处是:(1)消除了浮体效应,(2)减少了短通道效应,(3)优异的亚阈值特性,(4)降低了寄生源/漏电阻。

Floating-body effect free concave SOI-MOSFETs (COSMOS)
In order to overcome the degradation induced by floating body effects and to suppress the increase in parasitic source/drain resistances in thin-film silicon-on-insulator (SOI) MOSFETs, a concave SOI-MOSFET (COSMOS) is proposed. This structure realizes a partially thin-film SOI region, which is used as a fully depleted channel, and thick-film SOI regions, which are used as source/drain. The unique features of the COSMOS are found to be (1) elimination of the floating-body effects, (2) less short channel effect, (3) excellent subthreshold characteristics, and (4) reduction in parasitic source/drain resistances.<>
