SEMICONDUCTOR DEVICES AND METHOD OF MANUFACTURING THE SAME

摘要

Provided is a semiconductor device and a method of manufacturing the same. The semiconductor device includes a device isolation layer which defines the active regions of a substrate, and gate lines which intersects with the active regions and includes gate lines buried in the substrate. The gate lines include a first part on the device isolation layer, and a second part on the active region. The upper surface of the first part is lower than that of the second part.
