    摘要: A Schottky diode is fabricated by a sequence of fabrication by a sequence of fabrication steps. An active region of a semiconductor substrate is defined in which a Schottky diode is fabricated. At least first and second layers of insulating material are applied over the active area. A first layer of insulating material, having a first etching rate, is applied over the active area. A second layer of insulating material having a second, greater, etch rate is applied over the first layer of insulating material to a thickness that is about twice the thickness of the first layer of insulating material. The insulating material is patterned and a window is etched through the layers of insulating material to the semiconductor substrate. Metal is applied and unwanted metal is etched away leaving metal in the window forming a Schottky contact therein. One or more barrier layers may be employed.

    摘要: A magnetic random access memory (MRAM) using a schottky diode is disclosed. In order to achieve high integration of the memory device, a word line is formed on a semiconductor substrate without using a connection layer and a stacked structure including an MTJ cell, a semiconductor layer and a bit line is formed on the word line, thereby forming the schottky diode between the MTJ cell and the bit line. As a result, a structure of the device is simplified, and the device may be highly integrated due to repeated stacking.

    摘要: A method for producing a semiconductor component with adjacent Schottky (5) and pn (9) junctions positions in a drift area (2, 10) of a semiconductor material. According to the method, a silicon carbide substrate doped with a first doping material of at least 1018 cmnull3 is provided, and a silicon carbide layer with a second doping material of the same charge carrier type in the range of 1014 and 1017 cmnull3 is homo-epitaxially deposited on the substrate. A third doping material with a complimentary charge carrier is inserted, and structured with the aid of a diffusion and/or ion implantation, on the silicon carbide layer surface that is arranged far from the substrate to form pn junctions. Subsequently the component is subjected to a first temperature treatment between 1400null C. and 1700null C. Following this temperature treatment, a first metal coating is deposited on the implanted surface in order to form a Schottky contact and then a second metal coating is deposited in order to form an ohmic contact. Subsequently the first and second metal coatings are structured as designed.
