    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: 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: A method of fabricating a memory device is provided that may begin with forming a layered gate stack atop a semiconductor substrate and patterning a metal electrode layer stopping on the high-k gate dielectric layer of the layered gate stack to provide a first metal gate electrode and a second metal gate electrode on the semiconductor substrate. In a next process sequence, at least one spacer is formed on the first metal gate electrode atop a portion of the high-k gate dielectric layer, wherein a remaining portion of the high-k gate dielectric is exposed. The remaining portion of the high-k gate dielectric layer is etched to provide a first high-k gate dielectric having a portion that extends beyond a sidewall of the first metal gate electrode and a second high-k gate dielectric having an edge that is aligned to a sidewall of the second metal gate electrode.

    摘要: A method is provided for making a resistive polycrystalline semiconductor device, e.g., a poly resistor of a microelectronic element such as a semiconductor integrated circuit. The method can include: (a) forming a layered stack including a dielectric layer contacting a surface of a monocrystalline semiconductor region of a substrate, a metal gate layer overlying the dielectric layer, a first polycrystalline semiconductor region adjacent the metal gate layer having a predominant dopant type of either n or p, and a second polycrystalline semiconductor region spaced from the metal gate layer by the first polycrystalline semiconductor region and adjoining the first polycrystalline semiconductor region; and (b) forming first and second contacts in conductive communication with the second polycrystalline semiconductor region, the first and second contacts being spaced apart so as to achieve a desired resistance. In a variation thereof, an electrical fuse is formed which includes a continuous silicide region through which a current can be passed to blow the fuse. Some of the steps of fabricating the poly resistor or the electrical fuse can be employed simultaneously in fabricating metal gate field effect transistors (FETs) on the same substrate.

    摘要: Two trenches having different widths are formed in a semiconductor-on-insulator (SOI) substrate. An oxygen-impermeable layer and a fill material layer are formed in the trenches. The fill material layer and the oxygen-impermeable layer are removed from within a first trench. A thermal oxidation is performed to convert semiconductor materials underneath sidewalls of the first trench into an upper thermal oxide portion and a lower thermal oxide portion, while the remaining oxygen-impermeable layer on sidewalls of a second trench prevents oxidation of the semiconductor materials. After formation of a node dielectric on sidewalls of the second trench, a conductive material is deposited to fill the trenches, thereby forming a conductive trench fill portion and an inner electrode, respectively. The upper and lower thermal oxide portions function as components of dielectric material portions that electrically isolate two device regions.
