发明名称 Semiconductor memory device and method of making it.
摘要 In a semiconductor memory device, storage electrodes of two memory cells adjacent to each other are superimposed with each other, with their contours being substantially aligned. As a result, the storage electrodes are extended to cover two memory cell regions. The superimposed storage electrodes are electrically insulated from each other, and the upper storage electrode extends through the lower storage electrode.
