A gate electrode is formed on a gate insulator above a semiconductor substrate. Diffused regions are formed in a surface of the semiconductor substrate as sandwiching the gate electrode therebetween. A high-resistance layer is formed in the surface of the semiconductor substrate as electrically connected to the diffused region. A low-resistance layer is formed in the surface of the semiconductor substrate as electrically connected to the high-resistance layer. A drain electrode is connected to the low-resistance layer.
