    Abstract: A power MOSFET is provided. In this power MOSFET, a drift region is formed on a drain region having the same conductivity type as that of the drain region using a semiconductor substrate of a first conductivity type. A gate electrode is formed on the drift region, having a plurality of openings spaced apart from each other by a predetermined distance. The plurality of openings partially expose the drift region, and a gate insulating layer is interposed between the gate electrode and the drift region. A body region of a second conductivity type opposite to the first conductivity type is formed on a predetermined upper region of the drift region and extends from the opening to have a side overlapped by the gate electrode. A channel in the portion of the body region overlapped by the gate electrode is not formed and is adjacent to at least two facing sides of the opening. A source region is formed in the body region, including a first source region shaped in the form of a strip, the first source region contacting a portion where a channel is formed, and a second source region connecting the first source regions facing to each other. Also, a source electrode is electrically connected to the source region, and a drain electrode is electrically connected to the drain region.
