20130126962 | SEMICONDUCTOR DEVICE AND METHOD OF MANUFACTURING THE SAME - A semiconductor device and a method of manufacturing the same are provided. After spacers are formed on sidewalls of a pillar pattern and a photoresist pattern exposing an OSC formation region is formed on a semiconductor substrate including the pillar pattern and the spacer, processes for removing a spacer corresponding to the OSC formation region to form an OSC, removing the photoresist pattern, forming a bit line between the pillar patterns, an epitaxial layer on the pillar pattern, and forming a vertical gate and a storage node contact, are performed so that the OSC formation process can be simplified. In addition, the OSC formation process is performed in a state that the pillar pattern has a low height so that a failure such as a not-open failure caused in the OSC formation process can be prevented. | 05-23-2013 |
