    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: Multiple pitch-multiplied spacers are used to form mask patterns having features with exceptionally small critical dimensions. One of each pair of spacers formed mandrels is removed and alternating layers, formed of two mutually selectively etchable materials, are deposited around the remaining spacers. Layers formed of one of the materials are then etched, leaving behind vertically-extending layers formed of the other of the materials, which form a mask pattern. Alternatively, instead of depositing alternating layers, amorphous carbon is deposited around the remaining spacers followed by a plurality of cycles of forming pairs of spacers on the amorphous carbon, removing one of the pairs of spacers and depositing an amorphous carbon layer. The cycles can be repeated to form the desired pattern. Because the critical dimensions of some features in the pattern can be set by controlling the width of the spaces between spacers, exceptionally small mask features can be formed.

    Abstract: A wave division multiplexing (WDM) system is disclosed which accommodates shifts in the resonant frequency of optical modulators by using at least two carriers per optical communications channel and at least two resonant modulator circuits respectively associated with the carriers within each optical modulator. A first resonant modulator circuit resonates with a first carrier and a second resonates with a second carrier when there is a shift in resonance frequency of the at least two resonant optical modulator circuits. A switch circuit controls which carrier is being modulated by its respective resonant modulator circuit.

    Abstract: A magnetic cell structure including a nonmagnetic filament contact, and methods of fabricating the structure are provided. The magnetic cell structure includes a free layer, a pinned layer, an insulative layer between the free and pinned layers, and a nonmagnetic filament contact in the insulative layer which electrically connects the free and pinned layers. The nonmagnetic filament contact is formed from a nonmagnetic source layer, also between the free and pinned layers. The filament contact directs a programming current through the magnetic cell structure such that the cross sectional area of the programming current in the free layer 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.
