Abstract
In a semiconductor device and a method for manufacturing the same, a pillar pattern is formed in an alternating pattern and a one side contact (OSC) is formed without using a tilted ion implantation process or a mask, resulting in formation of a vertical gate. The semiconductor device includes an alternating or zigzag-type pillar pattern formed over a semiconductor substrate, a first hole formed between pillars of the pillar pattern, a passivation layer formed over a sidewall of the first hole, a second hole formed by partially etching a lower part of the first hole, a bit line formed in the second hole, and a contact formed at a lower part of the pillar pattern.
