Body-tied triple-gate NMOSFET fabrication using bulk Si wafer
We fabricated firstly body-tied triple-gate NMOSFETs that have fin top width of 30 nm, fin bottom width of 61 nm, fin height of 99nm, and gate length of 116nm. Fabrication process steps of the devices are compatible with that of conventional bulk planar channel MOSFET technology and explained in detail in this paper. This MOSFET shows excellent transistor characteristics, such as very low subthreshold swing, Drain Induced Barrier Lowering (DIBL) of 24mV/V, almost no body bias effect, and orders of magnitude lower I-SUB/I-D than planar channel DRAM cell transistors. By optimizing process further, it is expected that cost effective body-tied triple-gate MOSFETs can be applied to real Integrated Circuits (ICs). (C) 2004 Elsevier Ltd. All rights reserved.
