Abstract

In this study, $(Ba_{0.7}\;Sr_{0.3})TiO_3$ was coated on Pt/Ti/$SiO_2$/Si wafer by using Sol-Gel method. Coating process was repeated 3~5 times and then sintered at 750[$^{\circ}C$] for 1 hour. Each specimen was analyzed structure and electrical characteristics. In structure characteristics, EDX analyzed the samples ratio of the formation on the structural property. Thermal behavior was observed with TG-DTA and concluded that the heat-treatment of the samples was degreed 750[$^{\circ}C$]. Surface and section of thin films were observed with SEM.
