Semiconductor device and method of manufacturing the same
摘要:
Provided are a semiconductor memory device that permits increasing the degree of integration without decreasing the capacitance of the capacitor included in a memory cell, and a method of manufacturing the particular semiconductor memory device. Specifically, provided are a semiconductor memory device, comprising a semiconductor substrate, an interlayer insulating film formed on the semiconductor substrate, a first electrode formed on the interlayer insulating film, a first ferroelectric film formed on the first electrode, a second electrode formed on the first ferroelectric film, a second ferroelectric film formed on the second electrode, and a third electrode formed on the second ferroelectric film, and a method of manufacturing the particular semiconductor memory device.
