Methods of Manufacturing Semiconductor devices Having Buried Bit Lines
摘要：
A semiconductor device includes a semiconductor substrate having a first conductivity type and having an upper portion, a pair of bit lines extending in a first direction and doped with an impurity of a second conductivity type opposite to the first conductivity type and spaced from one another in the upper portion of the semiconductor substrate, a first line formed between the pair of bit lines having a plurality of alternating recessed device isolation regions and channel regions, with each of the channel regions contacting each bit line of the at least one pair of bit lines, and word lines formed at right angles to the first lines and covering the channel regions.
摘要（中）：

半导体器件包括具有第一导电类型并具有上部的半导体衬底，一对位线沿着第一方向延伸并且掺杂有与第一导电类型相反并且彼此间隔开的第二导电类型的杂质 所述半导体衬底的上部，形成在所述一对位线之间的第一线，所述第一线具有多个交替的凹陷器件隔离区域和沟道区域，其中每个沟道区域与所述至少一对位线的每个位线接触 以及与第一线成直角形成并覆盖沟道区的字线。
