A semiconductor device includes a deep N-type well region which may be formed by applying an ion-implantation process, using a mask, to a predetermined pattern over a portion of a semiconductor substrate over which an oxide film is formed, a dwell region which may be formed by applying an ion-implantation process, using a mask, to a predetermined pattern over a portion of the N-type well region, a shallow N-type well region and a drain region which may be respectively formed by applying an ion-implantation process, using a mask, to a predetermined pattern over a portion of the deep N-type well region, a source region which may be formed by applying an ion-implantation process, using a mask, to a predetermined pattern over a portion of the dwell region, a contact hole which may be formed by being filled with a metal after forming an inter-metal dielectric layer over a portion of the semiconductor substrate over which the source region is formed, and a metal line formed over a portion of the contact hole.
