We have investigated the nitridation of germanium substrate by our original high-density plasma source. Pure amorphous Ge$_3$N$_4$ layers without oxygen are obtained by the direct nitridation of clean Ge substrates. The conformal growth with smooth surface and sharp interface can be achieved in the Ge$_3$N$_4$ layers grown at 350 $^o$C, where the thickness of the Ge$_3$N$_4$ layers is 3.5 nm. In addition, in order to apply this Ge nitride to integrate high-k gate dielectrics with Ge and its alloy for FET-based devices, we have also investigated the thermal stability of the Ge nitride layers. As a result, we found that Ge$_3$N$_4$ layers resisted in N2 ambient around 550 $^o$C, and evaporated above 600 $^o$C. These results demonstrate that it is promising as a passivation layer for integrating high-k dielectric on high performance Ge substrate and is expected to shed light on the realization of Ge-based FETs. |
