  • Vertical Memory Devices and Methods of Manufacturing the Same
    Publication number: 20150200203
    Abstract: In a method of a vertical memory device, insulation layers and sacrificial layers are alternately and repeatedly formed on a substrate. A hole is formed through the insulation layers and the sacrificial layers that expose a top surface of the substrate. Then, an interior portion of the hole may be enlarged. A semiconductor pattern is formed to partially fill the enlarged portion of the hole. A blocking layer, a charge storage layer and a tunnel insulation layer may be formed on a sidewall of the hole and the semiconductor pattern. Then, the tunnel insulation layer, the charge storage layer and the blocking layer are partially removed to expose a top surface of the semiconductor pattern. A channel is formed on the exposed top surface of the semiconductor pattern and the tunnel insulation layer. The sacrificial layers are replaced with gate electrodes.

  • Method and apparatus of gasification under the integrated pyrolysis reformer system (IPRS)
    Patent number: 8858661
    Abstract: A gasification system reduces volume of a bulky carbonaceous feedstock by pyrolysis to bring about a significant reduction in volume. The system includes a pyrolysis chamber, a reformer, a syngas burner, and a syngas storage tank. Flue gas is provided from the chamber to the reformer. Hot gases are introduced to the reformer from the syngas burner. The pyrolysis reaction occurs in the reformer to produce syngas of at least 1200° C. Some of the produced syngas is used to heat the pyrolysis chamber and the rest returns to the reformer with the flue gas. The syngas burner is situated horizontally at the bottom of the reformer, while the pyrolysis chamber is situated vertically at the top of the reformer. The reformer is inclined relative to each of the syngas burner and the pyrolysis chamber.
