    摘要: A semiconductor fin having a doping of the first conductivity type and a semiconductor column are formed on a substrate. The semiconductor column and an adjoined end portion of the semiconductor fin are doped with dopants of a second conductivity type, which is the opposite of the first conductivity type. The doped semiconductor column constitutes an inner electrode of a capacitor. A dielectric layer and a conductive material layer are formed on the semiconductor fin and the semiconductor column. The conductive material layer is patterned to form an outer electrode for the capacitor and a gate electrode. A single-sided halo implantation may be performed. Source and drain regions are formed in the semiconductor fin to form an access transistor. The source region is electrically connected to the inner electrode of the capacitor. The access transistor and the capacitor collectively constitute a DRAM cell.

    摘要: A method forms an anti-fuse structure comprises a plurality of parallel conductive fins positioned on a substrate, each of the fins has a first end and a second end. A second electrical conductor is electrically connected to the second end of the fins. An insulator covers the first end of the fins and a first electrical conductor is positioned on the insulator. The first electrical conductor is electrically insulated from the first end of the fins by the insulator. The insulator is formed to a thickness sufficient to break down on the application of a predetermined voltage between the second electrical conductor and the first electrical conductor and thereby form an uninterrupted electrical connection between the second electrical conductor and the first electrical conductor through the fins.

    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.

The structure includes a semiconductor substrate having at least one patterned gate stack located within a pFET device region of the semiconductor substrate. The structure further includes extension regions located within the semiconductor substrate at a footprint of the at least one patterned gate stack. A channel region is also present and is located within the semiconductor substrate beneath the at least one patterned gate stack. The structure further includes a localized workfunction tuning area located within a portion of at least one of the extension regions that is positioned adjacent the channel region as well as within at least a sidewall portion of the at least one gate stack. The localized workfunction tuning area can be formed by ion implantation or annealing.

    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.
