    摘要: A method for processing a substrate comprising at least a buried oxide (BOX) layer and a semiconductor material layer is provided. The method includes etching the semiconductor material layer to form a vertical semiconductor material structure overlying the BOX layer, leaving an exposed portion of the BOX layer. The method further includes exposing a top surface of the exposed portion of the BOX layer to an oxide etch resistant species to form a thin oxide etch resistant layer overlying the exposed portion of the BOX layer.

    摘要: An electronic device can include a semiconductor fin with a first gate electrode adjacent to a first wall, and a second gate electrode adjacent to a second wall. In one embodiment, a conductive member can be formed overlying the semiconductor fin, and a portion of the conductive member can be reacted to form the first and second gate electrodes. In another embodiment, a patterned masking layer can be formed including a masking member over a gate electrode layer, and portion of the masking member overlying the semiconductor fin can be removed. In still another embodiment, a first fin-type transistor structure can include the semiconductor fin, the first and second gate electrodes, and a first insulating cap. The electronic device can also include a second fin-type transistor structure having a second insulating cap thicker than the first insulating cap.

    摘要: A metal layer is formed over a metal oxide, where the metal oxide is formed over a semiconductor substrate. A predetermined critical dimension of the metal layer is determined. A first etch is performed to etch the metal layer down to the metal oxide and form footings at the sidewalls of the metal layer. A second etch to remove the footings to target a predetermined critical dimension, wherein the second etch is selective to the metal oxide. In one embodiment, a conductive layer is formed over the metal layer. The bulk of the conductive layer may be etched leaving a portion in contact with the metal layer. Next, the portion left in contact with the metal layer may be etched using chemistry selective to the metal layer.
