    • The stacked capacitor cell is mfd. by (a) forming a field oxide film (2), a gate oxide film (3), a gate polysilicon film (4), a gate cap oxide film (5) and a gate sidewall nitride film (6) on the substrate, and then implanting n+ or n- ion to form a source/ drain, (b) depositing an insulating oxide film (7), forming a buried contact, and then etching the residual oxide film (7), (c) forming a polysilicon film (4a) for a storage node, and then photoetching it to form the storage node, and (d) depositing a capacitor dielectric film (8) and a polysilicon film (9) for a plate, and then photoetching and partially lifting off the films (8,9) to form the plate.
    • 堆叠的电容器单元是mfd。 通过(a)在基板上形成场氧化膜(2),栅极氧化膜(3),栅极多晶硅膜(4),栅极氧化膜(5)和栅极侧壁氮化物膜(6) 然后注入n +或n-离子以形成源极/漏极,(b)沉积绝缘氧化物膜(7),形成掩埋接触,然后蚀刻残余氧化物膜(7),(c)形成多晶硅膜 (4a),然后对其进行光刻以形成存储节点,以及(d)沉积用于板的电容器电介质膜(8)和多晶硅膜(9),然后光刻并部分地剥离膜 (8,9)以形成板。
