Fully-depleted, ultra-thin SIMOX/CMOS is a suitable technology to achieve low voltage and
high speed application because of its capability of low Vth operation. However, large
resistivity of diffusion area is an issue. In this paper, a thin salicidation layer was adopted to
decrease the sheet resistivity of the ultra-thin SIMOX layer. Good transistor characteristics
with sheet resistivity less than one tenth of the non-silicided diffusion resistivity were
achieved, and no degradation of the transistor characteristics was observed.
