摘要:
A semiconductor device manufacturing method has a step forming a transistor layer portion on a semiconductor substrate, and a step forming a ferroelectric capacitor portion including a lower electrode, a ferroelectric substance and an upper electrode above the transistor layer portion, wherein the step forming the ferroelectric capacitor portion includes adjusting an area of the upper electrode on the basis of manufacturing parameters of the ferroelectric capacitor portion.
