Abstract
In a method of fabricating a semiconductor device, a first mask pattern is formed on a substrate. The first mask pattern has a first opening formed to expose the substrate. An oxidation barrier region is formed in the substrate exposed by the first opening, and the first mask pattern is patterned to form a second mask pattern having a second opening. A gate insulation layer is formed on the substrate exposed by the second opening. The gate insulation layer has a variable thickness.
