A surface profile sensor includes an interlayer insulating film provided with a planarized upper surface formed above a semiconductor substrate, a detection electrode film formed on the interlayer insulating film, an upper insulating film formed on the detection electrode film and the interlayer insulating film and including the surface on which a silicon nitride film is exposed, and a protection insulating film deposited on the upper insulating film and made of a tetrahedral amorphous carbon (ta-C) film including a window formed on the detection electrode film. |
