Abstract:
A semiconductor device comprising:an element formation region divided by an element isolation insulation film at a main surface of a semiconductor substrate; a semiconductor element including a first electrode formed to traverse said element formation region, and one pair of first impurity regions of a predetermined conductivity type formed at said element formation region so as to sandwich said first electrode from both sides, and having a first impurity concentration; a second electrode formed at said element formation region, extending parallel to and apart from said first electrode by a predetermined distance, and having one end located within said element formation region; a first sidewall insulation film and a second sidewall insulation film formed on respective sides of said first and second electrodes, at least covering said first impurity region sandwiched by said first and second electrodes, and exposing said first impurity region in close proximity to said one end of said second electrode; and a second impurity region formed from one end of the second electrode towards a longitudinal direction, and surrounded by one of said pair of first impurity regions at the main surface of the semiconductor substrate.
