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.
Claims7
A three-dimensional magnetic apparatus characterized by a plurality of magnetic bubble supporting regions located on a continuous substrate wherein said substrate is folded on itself to form said three-dimensional apparatus and means for providing a magnetic field for supporting and propagating magnetic bubbles in said regions which is common to all said regions.
A three-dimensional magnetic bubble device comprising,
- a continuous flexible substrate folded on itself providing at least one layer overlying at least one other layer,
- a plurality of pseudo-chips deposited on said flexible substrate, each of said pseudo-chips comprising a material suitable for supporting magnetic bubbles,
- thin-film interconnection means between at least some of said pseudo-chips, and
- means for providing a common magnetic field for supporting and propagating bubbles in said pseudo-chips, said common magnetic field common to all said pseudo-chips.
