Abstract
A three-dimensional magnetic bubble device formed by depositing, on a flexible substrate, a plurality of pseudo-chips of amorphous metallic film capable of supporting magnetic bubbles. These pseudo-chips are interconnected by thin-film conductors also deposited on the flexible substrate. The substrate is then folded, on itself, a number of times to produce a three-dimensional magnetic bubble device. Optionally, a low temperature lamination step can be employed to complete the process. The folding step or steps, result in a number of layers, to which a common rotating magnetic field may be applied for propagation purposes.
