In a semiconductor device having line type active regions and a method of fabricating the semiconductor device, the semiconductor device includes a device isolation layer which defines the line type active regions in a in a semiconductor substrate. The device also includes a moisture detection device that detects a quantity of moisture on the vehicle and a controlling device that controls the wiping action of the wiper based on a wiping sensitivity to the quantity of moisture detected. Alternatively, the sample portion is suspected, but not yet confirmed, to have the selected ferrimagnetic constituent associated with it.
