Abstract

In the preparation of SOI films by Zone Melting Recrystallization (ZMR) a cap layer is necessary to avoid the beading up of a silicon film when it is molten over silicon. This is a consequence of a bad wetting of liquid Si on SiO2. We report the successful application of a plasma nitridation treatment of the capping oxide. We compare the behaviour of the liquid silicon films during ZMR for different capping structures. The modification of the interface is investigated by using Auger analysis. We show that a range of nitrogen accumulation at the interface provides a good wetting.
