    摘要: Memory devices having improved BVdss characteristics and methods of making the memory devices are provided. The memory devices contain bitline dielectrics on bitlines of a semiconductor substrate; first spacers adjacent the side surfaces of the bitline dielectrics and on the upper surface of the semiconductor substrate; a trench in the semiconductor substrate between the first spacers; and second spacers adjacent the side surfaces of the trench. By containing the trench and the first and second spacers between the bitlines, the memory device can improve the electrical isolation between the bitlines, thereby preventing and/or mitigating bitline-to-bitline current leakage and increasing BVdss.
