Abstract: PURPOSE: A method is provided for the semiconductor memory which is improved in reliability by preventing the lowering of capacitance and defective insulation, especially, electrode separation caused by the formation of the passivation film (insulating film) of a capacitor using a high ferroelectric material by plasma processing at a relatively low temperature and a method for manufacturing the memory. Therefore, lowering of capacitance, defective insulation, and especially, electrode separation, which are caused by the formation of the passivation film (insulating film), can be prevented. In addition, the occurrence of defective insulation can be reduced by suppressing the lowering of the capacitance when an alternating electric field is impressed. When a ferroelectric material is used as the dielectric film, moreover, such an effect as an increase in residual polarization, a decrease in coercive voltage, etc., can be obtained.

An oxygen introducing layer (104) is further formed on the surface of the thin film (103) constituting the capacitor insulating film. In the manufacturing process of the memory, for example, the oxygen introducing layer (104) is formed on the surface of the high ferroelectric material (103) by introducing oxygen to the boundary between the electrode (105) and the material (103) by conducting heat treatment in an oxygen atmosphere before the protective insulating film (SiO2 passivation film) (106) is formed by plasma processing after the formation of the electrode (105).
