A DRAM cell with an improved trench structure, capacitor has been developed for 16M DRAMs. The capacitor is formed within a trench with polysilicon to polysilicon structure. Covering the storage electrode with the cell-plate makes this cell free from punch-through between adjacent cells. The whole capacitor is coverd with a dielectric layer and there is no… CONTINUE READING
