0.1- mu m-gate, ultrathin-film CMOS devices using SIMOX substrate with 80-nm-thick buried oxide layer

Abstract

A 0.1- mu m-gate CMOS/SIMOX (separation by implanted oxygen) has been successfully fabricated using high quality SIMOX substrates and an advanced design concept for the subquarter-micron region based on a simple device model. In addition, both 85-nm-gate n- and p-MOSFETs/SIMOX with 8-nm-thick silicon active layer have been realized. High parasitic resistance in the source and drain regions of the 0.1- mu m-gate CMOS/SIMOX tends to increase the propagation delay time. However, 0.1- mu m-gate CMOS/SIMOX devices with a delay time as low as 10 ps can be obtained by reducing the parasitic resistance.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
