Semiconductor device with vertical gate and method for fabricating the same
Abstract:
A semiconductor device includes a substrate; a plurality of active pillars formed over the substrate; bulb-type trenches, each of the bulb-type trenches formed inside the substrate between the active pillars; buried bit lines, each of the buried bit lines being formed on a sidewall of a respective one of the bulb-type trenches; and vertical gates, each of the vertical gates being formed to surround a sidewall of a respective one of the active pillars.
