Abstract:
A semiconductor device includes a device isolation region defining an active region in a substrate, and gate structures buried in the active region of the substrate. At least one of the gate structures includes a gate trench, a gate insulating layer conformally formed on an inner wall of the gate trench, a gate barrier pattern conformally formed on the gate insulating layer disposed on a lower portion of the gate trench, a gate electrode pattern formed on the gate barrier pattern and filling the lower portion of the gate trench, an electrode protection layer conformally formed on the gate insulating layer disposed on an upper portion of the gate trench to be in contact with the gate barrier pattern and the gate electrode pattern, a buffer oxide layer conformally formed on the electrode protection layer, and a gate capping insulating layer formed on the buffer oxide layer to fill the upper portion of the gate trench.

Claim (Index 1):
A semiconductor device, comprising:\n a device isolation region defining an active region in a substrate; and gate structures buried in the active region of the substrate, wherein at least one of the gate structures comprises: a gate trench; a gate barrier pattern disposed on a lower portion of the gate trench; a gate electrode pattern formed on the gate barrier pattern and filling the lower portion of the gate trench; a buffer oxide layer formed on the gate electrode pattern; and a gate capping insulating layer formed on the buffer oxide layer to fill the upper portion of the gate trench, wherein the gate barrier pattern have a top surface which is lower that top of the gate electrode pattern.
