    • A conductive pattern having a surface including silicon is formed on a substrate of a semiconductor device and a conduction region having a surface including silicon is formed in the substrate. A radio frequency etching process is performed ex-situ to remove impurities from a resultant structure and to improve surface characteristics of the conduction region. Residues generated during the radio frequency etching process are removed from the conductive pattern and the conduction region by a cleaning process. A metal film is formed on the conductive pattern and the conduction region. A silicide film is formed on the conductive pattern and the conduction region by reacting metal of the metal film and silicon in the conductive pattern and the conduction region. With a radio frequency sputtering process and a wet cleaning process, a metal silicide film having a uniform phase may be stably formed.
    • 在半导体器件的衬底上形成具有包括硅的表面的导电图案,并且在衬底中形成具有包括硅的表面的导电区域。 非原位地进行射频蚀刻处理以从所得结构中去除杂质并改善导电区域的表面特性。 在射频蚀刻工艺中产生的残留物通过清洁处理从导电图案和导电区域中去除。 在导电图案和导电区域上形成金属膜。 通过金属膜的金属和导电图案中的硅和导电区域之间的反应,在导电图案和导电区域上形成硅化物膜。 通过射频溅射法和湿式清洗法,可以稳定地形成具有均匀相的金属硅化物膜。
