In order to remove a nature oxide layer or impurity of the plug contact hole, a cleaning process is performed. A plug polysilicon layer(28) is formed on the total structure in order to make the plug contact hole be buried. The plug polysilicon layer except a part to be used as a plug and the protective layer are partially removed, thereby forming a plug. An upper wiring layer(29) is formed on the plug.
