  • Patent number: 6765252
    Abstract: Disclosed are a DRAM cell having independent and asymmetric source/drain regions and a method of forming the same. The DRAM cell has an asymmetric structure in which source junctions are thick and drain junctions are thin. Therefore, the source/drain junctions have an asymmetric configuration via separate ion injection steps independent from each other, thereby preventing leakage current due to punch-through. Also, it is not necessary to form an ion injection layer for restraining punch-through, and a relatively low value of electric field is applied to the junctions to prolong refresh time. Further, the relatively thick spacer can be formed adjacent to the source regions thereby decreasing GIDL and further reducing electric field.
