    摘要: A magnetic data track used in a magnetic shift register memory system may be fabricated by forming a multilayered stack of alternating dielectric and/or silicon layers. Vias of approximately 10 microns tall with a cross-section on the order of 100 nm×100 nm are etched in this multilayered stack of alternating layers. Vias may be etched form smooth or notched walls. Vias are filled by electroplating layers of alternating types of ferromagnetic or ferrimagnetic metals. The alternating ferromagnetic or ferrimagnetic layers are comprised of magnetic materials with different magnetization or magnetic exchange or magnetic anisotropies. These different magnetic characteristics allow the pinning of magnetic domain walls at the boundaries between these layers. Alternatively, vias are filled with a homogeneous ferromagnetic material. Magnetic domain walls are formed by the discontinuity in the ferromagnetic or ferromagnetic material that occurs at the notches or at the protuberances along the via walls.

In an exemplary embodiment, the structure includes a deep trench isolation formed between a memory storage region of the semiconductor device and a logic circuit region of the semiconductor device, the deep trench isolation being filled with an insulative material. The deep trench isolation thereby prevents the propagation of crystal defects generated in the logic circuit region from propagating into the memory storage region.

    摘要: This invention relates to a bipolar transistor which incorporates, in a raised base regime, an emitter, collector pedestal and intrinsic and extrinsic bases all of which are self-aligned. The invention also relates to a process for fabricating such devices which obtains the self-alignment of the above mentioned elements using a single lithographic and masking step. The structure of the transistor, in addition to having the self-algined elements, incorporates a composite dielectric isolation layer which not only permits the carrying out of a number of functions during device fabrication but also provides for desired electrical characteristics during device operation. The composite isolation layer consists of an oxide layer adjacent the semiconductor surface; a nitride layer on the oxide layer and an oxide layer on the nitride layer in the final structure of the device. The last mentioned oxide layer starts out early in the fabrication process as a layer of oxidizable material, preferably polycrystalline silicon, which, at later steps in the process, acts as an etch-stop in its unoxidized state and as a memory element and mask in its oxidized state when a self-aligned datum element is removed and the thus exposed underlying dielectric elements must be removed to provide a planar emitter opening. The resulting transistor includes a planar emitter-emitter contact interface which provides for fine control of emitter depth in the underlying intrinsic base region.
