In a reliable semiconductor device and a method of fabricating the semiconductor device, a difference in height between upper surfaces of a cell region and a peripheral region (also referred to as a level difference) is minimized by optimizing dummy gate parts. The semiconductor device includes a semiconductor substrate including a cell region and a peripheral region surrounding the cell region, a plurality of dummy active regions surrounded by a device isolating region and formed apart from each other, and a plurality of dummy gate parts formed on the dummy active regions and on the device isolating regions located between the dummy active regions, wherein each of the dummy gate parts covers two or more of the dummy active regions.

A method of fabricating a non-volatile memory integrated circuit device and a non-volatile memory integrated circuit device fabricated by using the method are provided. A device isolation region is formed in a substrate to define a cell array region and a peripheral circuit region. A plurality of first and second pre-stacked gate structures is formed in the cell array region, and each has a structure in which a lower structure, a conductive pattern and a first sacrificial layer pattern are stacked. Junction regions are formed in the cell array region. Spacers are formed on side walls of the first and second pre-stacked gate structures. A second sacrificial layer pattern filling each space between the second pre-stacked gate structures is formed. The first sacrificial layer pattern is removed from each of the first and second pre-stacked gate structures. A damascene metal layer pattern is formed in each of spaces of the first and second pre-stacked gate structures from which the first sacrificial layer pattern is removed, thus completing first and second stacked gate structures. The second sacrificial layer pattern is removed. A stop layer is formed on top surfaces of the first stacked gate structures, top surfaces and side walls of the second stacked gate structures, and a top surface of the substrate.
