A method for forming a gas dielectric with support structure on a semiconductor device structure provides low capacitance and adequate support for a conductor of the semiconductor device structure. A conductive structure, such as via or interconnect, is formed in a wiring-layer dielectric. A support is then formed that connects to the conductive structure, the support including an area thereunder. The wiring-layer dielectric is then removed from the area to form a gas dielectric.

A method of patterning which provides images substantially smaller than that possible by lithographic techniques is provided. In the method of the invention, a substrate has a memory layer and a sacrificial layer formed thereon. An image is patterned onto the memory layer by protecting an edge during an etching step using chemical oxide removal (COR) processes, for example. Another edge is memorized in the layer. The sacrificial layer is removed to expose another memorized edge, which is used to define a pattern in an underlying layer.

A memory gain cell for a memory circuit, a memory circuit formed from multiple memory gain cells, and methods of fabricating such memory gain cells and memory circuits. The memory gain cell includes a storage device capable of holding a stored electrical charge, a write device, and a read device. The read device includes a fin of semiconducting material, electrically-isolated first and second gate electrodes flanking the fin, and a source and drain formed in the fin adjacent to the first and the second gate electrodes. The first gate electrode is electrically coupled with the storage device. The first and second gate electrodes are operative for gating a region of the fin defined between the source and the drain to thereby regulate a current flowing from the source to the drain. When gated, the magnitude of the current is dependent upon the electrical charge stored by the storage device.

Conductive paths in an integrated circuit are formed using multiple undifferentiated carbon nanotubes embedded in a conductive metal, which is preferably copper. Preferably, conductive paths include vias running between conductive layers. Preferably, composite vias are formed by forming a metal catalyst pad on a conductor at the via site, depositing and etching a dielectric layer to form a cavity, growing substantially parallel carbon nanotubes on the catalyst in the cavity, and filling the remaining voids in the cavity with copper. The next conductive layer is then formed over the via hole.
