    Abstract

    The realisation a 0.25 μm NMOSFET using arsenic implanted GexSi1-xas gate material, with minimal changes in an existing process is reported. The etching of this gate material does not pose a problem and the underlying thin gate oxide is hardly attacked. We will show good transistor characteristics for both a 6nm and a 4.5 nm oxide thickness. VTroll-off is comparable for the poly-Si and poly-GexSi1-xgates.
