Abstract
Provided is a semiconductor device having bit line expanding islands, which are formed underneath bit lines to reliably expand and connect the bit lines. The semiconductor device includes: a semiconductor layer in which an isolation region and an active region are defined; an insulating layer, which is formed on the semiconductor layer; a plurality of bit lines, which are formed on the insulating layer; and one or more bit line expanding islands, which are formed inside the insulating layer and are electrically connected to a lower portion of at least one of the plurality of bit lines
