A method of manufacturing a semiconductor apparatus comprises the steps of forming, on a surface of a semiconductor substrate, an MIS transistor including a drain region and a source region each formed of an impurity diffusion region, forming an insulation film on the semiconductor substrate after the MIS transistor has been formed, selectively forming contact holes in the insulation film, embedding, into the contact hole, a capacitor contact plug having a lower end which is in contact with one of the drain region and the source region of the MIS transistor, forming a ferroelectric capacitor having a lower electrode, a ferroelectric film and an upper electrode on the insulation film after the capacitor contact plug has been formed, and forming an electric wire for establishing a connection between the upper electrode of the ferroelectric capacitor and an upper surface of the capacitor contact plug.
