  • Patent number: 7276765
    Abstract: A buried transistor particularly suitable for SOI technology, where the transistor is fabricated within a trench in a substrate and the resulting transistor incorporates completely isolated active areas.

  • Patent number: 7247227
    Abstract: In devices such as flat panel displays, an aluminum oxide layer is provided between an aluminum layer and an ITO layer when such materials would otherwise be in contact to protect the ITO from optical and electrical defects sustained, for instance, during anodic bonding and other fabrication steps. This aluminum oxide barrier layer is preferably formed either by: (1) partially or completely anodizing an aluminum layer formed over the ITO layer, or (2) an in situ process forming aluminum oxide either over the ITO layer or over an aluminum layer formed on the ITO layer. After either of these processes, an aluminum layer is then formed over the aluminum oxide layer.

    Abstract: Provided are methods for fabricating semiconductor devices incorporating a fin-FET structure that provides body-bias control, exhibits some characteristic advantages associated with SOI structures, provides increased operating current and/or reduced contact resistance. The methods for fabricating semiconductor devices include forming insulating spacers on the sidewalls of a protruding portion of a first insulation film; forming a second trench by removing exposed regions of the semiconductor substrate using the insulating spacers as an etch mask, and thus forming fins in contact with and supported by the first insulation film. After forming the fins, a third insulation film is formed to fill the second trench and support the fins. A portion of the first insulation film is then removed to open a space between the fins in which additional structures including gate dielectrics, gate electrodes and additional contact, insulating and storage node structures may be formed.
