(Zr, Sn)TiO4 is considered as a promising dielectric material for microwave devices owing to the temperature stability of capacitance and excellent microwave properties. Preferential (111)-oriented (ZrSn)TiO4 thin film was obtained by an ArF laser ablation. Properties of the crystallized film were as follows; the temperature coefficient of capacitance TCC was 17.6ppm/°C at 3MHz and the dielectric constant εr, 38 in the microwave range of 1GHz˜10GHz. It has turned out that the crystallization of this material is quite effective for improving dielectrical properties. Surface morphologies were observed by atomic force microscope(AFM). Grains grew on the crystallized film at 1 μm × 1 μm size.
