A method for fabricating a ferroelectric memory device, including terminating a surface of the interlayer insulation film and a surface of the contact plug with an OH group; forming a layer containing Si, oxygen and a CH group on the surface of the interlayer insulation film and the contact hole terminated with the OH group by coating a Si compound containing a Si atom and a CH group in a molecule thereof; converting the layer containing Si, oxygen and the CH group to a layer containing nitrogen at a surface thereof, by substituting the CH group in the layer containing Si, oxygen and the CH group at least at a surface part thereof with nitrogen atoms; and forming a layer showing self-orientation on the surface containing nitrogen.
