摘要: A semiconductor memory device including a plurality of cells arranged in matrix manner, each the transfer transistor constituted by gate electrode, insulating film, source region and drain region, charge storage capacitor node, dielectric film plate node cylindrical lower electrode formed above via an layer on connected to one transistor, cover type upper with electrode. By composite structure having cylinder shape structure, it is possible utilize efficiently three-dimensional space thereby achieve increase capacitance.
