Abstract

A method for fabricating a ferroelectric memory having memory cells arranged in arrays, wherein an AlOfilm (), a Pt film (), a PZT film () and IrOfilm () are formed on an interlayer insulation film. At the time of forming a top electrode, the IrOfilm () is patterned using a resist mask having a part extending in the row direction, and then patterned using a resist mask having a part extending in the column direction. Consequently, a top electrode of the IrOfilm () having a rectangular plan view is formed at the intersection of these resist masks.
