    Abstract: A magnetic cell structure including a nonmagnetic bridge, and methods of fabricating the structure are provided. The magnetic cell structure includes a free layer, a pinned layer, and a nonmagnetic bridge electrically connecting the free layer and the pinned layer. The shape and/or configuration of the nonmagnetic bridge directs a programming current through the magnetic cell structure such that the cross sectional area of the programming current in the free layer of the structure is less than the cross section of the structure. The decrease in the cross sectional area of the programming current in the free layer enables a lower programming current to reach a critical switching current density in the free layer and switch the magnetization of the free layer, programming the magnetic cell.

    Abstract: A method of forming a substrate with isolation areas suitable for integration of electronic and photonic devices is provided. A common reticle and photolithographic technique is used to fabricate a mask defining openings for etching first and second trench isolation areas in a substrate, with the openings for the second trench isolation areas being wider than the openings for the first trench isolation areas. The first and second trench isolation areas are etched in the substrate through the mask. The second trench isolation areas are further etched to the deeper than the first trench isolation areas. The trench isolation areas are filled with oxide material. Electrical devices can be formed on the substrate and electrically isolated by the first trench isolation areas and photonic devices can be formed over the second trench isolation areas and be optically isolated from the substrate.

    Abstract: An integrated circuit and a method of formation provide a contact area formed at an angled end of at least one linearly extending conductive line. In an embodiment, conductive lines with contact landing pads are formed by patterning lines in a mask material, cutting at least one of the material lines to form an angle relative to the extending direction of the material lines, forming extensions from the angled end faces of the mask material, and patterning an underlying conductor by etching using said material lines and extension as a mask. In another embodiment, at least one conductive line is cut at an angle relative to the extending direction of the conductive line to produce an angled end face, and an electrical contact landing pad is formed in contact with the angled end face.
