Abstract: Ferromagnetic material is included selectively in semiconductor elements to enable handling of such elements during fabrication by means of magnetic fields. The invention is particularly, although not exclusively, adapted to beam leaded semiconductor devices in which ferromagnetic material may be included selectively in the beam leads as well as in or on the semiconductor body itself. Magnetic manipulation for a wide variety of purposes is disclosed.
