摘要： FinFETs are provided with a body contact on a top surface of a semiconductor fin. The top body contact may be self-aligned with respect to the semiconductor fin and the source and drain regions. Alternately, the source and drain regions may be formed recessed from the top surface of the semiconductor fin. The body or an extension of the body may be contacted above the channel or above one of the source and drain regions. Electrical shorts between the source and drain and the body contacts are avoided by the recessing of the source and drain regions from the top surface of the semiconductor fin.

摘要： In one embodiment, a mandrel and an outer dummy spacer may be employed to form a first conductivity type region. The mandrel is removed to form a recessed region wherein a second conductivity type region is formed. In another embodiment, a mandrel is removed from within shallow trench isolation to form a recessed region, in which an inner dummy spacer is formed. A first conductivity type region and a second conductivity region are formed within the remainder of the recessed region. An anneal is performed so that the first conductivity type region and the second conductivity type region abut each other by diffusion. A gate electrode is formed in self-alignment to the p-n junction between the first and second conductivity regions. The p-n junction controlled by the gate electrode, which may be sublithographic, constitutes an inventive tunneling effect transistor.

摘要： Trench anti-fuse structures, design structures embodied in a machine readable medium for designing, manufacturing, or testing a programmable integrated circuit. The anti-fuse structure includes a trench having a plurality of sidewalls that extend into a substrate, a doped region in the semiconductor material of the substrate proximate to the sidewalls of the trench, a conductive plug in the trench, and a dielectric layer on the sidewalls of the trench. The dielectric layer is disposed between the conductive plug and the doped region. The dielectric layer is configured so that a programming voltage applied between the doped region and the conductive plug causes a breakdown of the dielectric layer within a region of the trench. The trench sidewalls are arranged with a cross-sectional geometrical shape that is independent of position between a bottom wall of the deep trench and a top surface of the substrate.

摘要： A method includes forming patterned lines on a substrate having a predetermined pitch. The method further includes forming spacer sidewalls on sidewalls of the patterned lines. The method further includes forming material in a space between the spacer sidewalls of adjacent patterned lines. The method further includes forming another patterned line from the material by protecting the material in the space between the spacer sidewalls of adjacent patterned lines while removing the spacer sidewalls.
