Abstract
A multi-layered package for a magnetic domain device including self-contained in-plane switching magnetic field coils surrounding one or more magnetic domain device chips and a permanent magnet surrounding the switching magnetic field coils. The switching coils are formed by two printed circuit layers, each layer comprising an insulating substrate having striped conductive patterns orthogonally oriented relative to each other on the opposite surfaces of the insulating layer. The ends of the striped conductors on one printed circuit layer are connected to the ends of the corresponding striped pattern on the other printed circuit layer so as to form one of the switching coils. The ends of the other pair of striped conductive patterns are similarly connected to form the second switching coil. The magnetic domain device chips are placed inside the formed switching coils which, in turn, are surrounded by the permanent magnet.
