    摘要: Techniques for forming devices, such as transistors, having vertical junction edges. More specifically, shallow trenches are formed in a substrate and filled with an oxide. Cavities may be formed in the oxide and filled with a conductive material, such a doped polysilicon. Vertical junctions are formed between the polysilicon and the exposed substrate at the trench edges such that during a thermal cycle, the doped polysilicon will out-diffuse doping elements into the adjacent single crystal silicon advantageously forming a diode extension having desirable properties.

    摘要: The present invention relates to methods for forming microelectronic structures in a semiconductor substrate. The method includes selectively removing dielectric material to expose a portion of an oxide overlying a semiconductor substrate. Insulating material may be formed substantially conformably over the oxide and remaining portions of the dielectric material. Spacers may be formed from the insulating material. An isolation trench etch follows the spacer etch. An optional thermal oxidation of the surfaces in the isolation trench may be performed, which may optionally be followed by doping of the bottom of the isolation trench to further isolate neighboring active regions on either side of the isolation trench. A conformal material may be formed substantially conformably over the spacer, over the remaining portions of the dielectric material, and substantially filling the isolation trench. Planarization of the conformal material may follow.

    摘要: A semiconductor magnetic memory device has a magnetic tunneling junction formed over a memory cell. The memory cell has a control gate surrounded by a floating gate. The floating gate is coupled to the magnetic tunneling junction through a pinning layer that maintains the magnetic orientation of the lower magnetic layer of the junction. A current through a selected word line, coupled to the control gate, generates a first magnetic field. A current through a cell select line generates a second magnetic field that is orthogonal to the first magnetic field. This changes the magnetic orientation of the upper magnetic layer of the junction to lower its resistance, thus allowing a write/erase voltage on a program/erase line to program/erase the floating gate.
