Abstract:
1. A method for fabricating a flux concentrating system for use in a magnetoelectronics device, the method comprising the steps of: providing a bit line formed in a substrate, wherein said bit line overlies and is magnetically coupled to a magnetoelectronic element or a magnetic memory unit; forming a first material layer overlying said bit line and said substrate; etching to form a trench in said first material layer, said trench disposed proximate to said bit line; depositing a cladding layer in said trench, said cladding layer having at least one side surface and a bottom surface and configured to direct magnetic flux produced by a current flowing through said bit line; forming a buffer material layer proximate to said at least one side surface and overlying said bottom surface of said cladding layer; and removing a portion of said buffer material layer and a portion of said cladding layer.
