Abstract

In a semiconductor device, and a method of fabricating the same, the semiconductor device includes a semiconductor substrate having a cell region and a peripheral circuit region, a portion of the semiconductor substrate in the cell region and in the peripheral circuit region including an isolation region defining an active region, a portion of the active region protruding above an upper surface of the isolation region to define at least two active channels, a gate dielectric layer formed over the active region of the semiconductor substrate including the at least two protruding active channels, a gate electrode formed over the gate dielectric layer and the isolation region of the semiconductor substrate, and a source/drain region formed in the active region of the semiconductor substrate on either side of the gate electrode.
