A small area Josephson tunnel junction is fabricated with the suspended metal mask made ofordinary razor blades.The junction overlap is formed by two successive evaporations ofsuperconductor materials at oblique angles.The advantages of this technique are that thefabrication processes can be performed continuously without opening the evaporation chamber andalso it is suitable for making a small area tunnel junctions.The Ⅰ-Ⅴ characteristic of a tunneljunction made by this technique has been taken at 4.2K.
