Abstract

We used a polycrystalline YSZ film deposited on the quartz substrate as a seed layer to enhance crystallization of the Si film deposited on it. The YSZ film was deposited by reactive sputtering at less than 50°C and the preferential orientation was (111). The 60-nm-thick Si film was deposited by e-beam evaporation method on the substrate with and without the YSZ film. It was found that the crystallization of the Si film deposited on the YSZ film occurs but not without the YSZ film at the temperature of 515°C. The SEM image of the Secco-etched Si film showed that the crystallized Si film consisted of ~50-nm-size grains and, from the TEM image, it is supposed that the Si grains are grown directly from the YSZ film.
