    • PURPOSE: A method for manufacturing a semiconductor device is provided to improve the integration of the semiconductor device by reducing margin between a gate electrode and a contact hole to prevent a contact hole extension phenomenon by an etching process to remove a natural thin film. CONSTITUTION: A transistor including a gate electrode, a source region and a drain region are formed on a substrate(S110). An interlayer dielectric layer is formed to cover the transistor(S120). A natural thin film is formed on the upper side of the source and drain regions and a contact hole formed in the interlayer dielectric layer(S130). The natural thin film is selectively removed by an etching process under a non-plasma atmosphere(S140). An ohmic contact layer is formed in the source and drain regions without the natural thin film(S150). A contact plug is formed by filling the contact hole with conductive materials(S160).
