    Abstract: A vertical MOS transistor includes a substrate, a metal line over the substrate, a semiconductor pillar, a gate dielectric layer surrounding the semiconductor pillar, and a metal gate surrounding the gate dielectric layer. The metal line is under a bottom surface of the semiconductor pillar. The semiconductor pillar is grown by using the bottom-up growing in low temperature to reduce turn off leakage current (Ioff), short channel effect, thermo-budget, and provide high electron mobility.

  • Publication number: 20190157423
    Abstract: A semiconductor arrangement and method of formation are provided. The semiconductor arrangement comprises a conductive contact in contact with a substantially planar first top surface of a first active area, the contact between and in contact with a first alignment spacer and a second alignment spacer both having substantially vertical outer surfaces. The contact formed between the first alignment spacer and the second alignment spacer has a more desired contact shape then a contact formed between alignment spacers that do not have substantially vertical outer surfaces. The substantially planar surface of the first active area is indicative of a substantially undamaged structure of the first active area as compared to an active area that is not substantially planar. The substantially undamaged first active area has a greater contact area for the contact and a lower contact resistance as compared to a damaged first active area.

  • Patent number: 10163690
    Abstract: Two-dimensional (2-D) interconnects in a one-dimensional (1-D) patterning layout for integrated circuits is disclosed. This disclosure provides methods of connecting even or odd numbered lines that are in the x-direction of a 1-D patterning layout through 2-D interconnects in the y-direction. Depending on device design needs, 2-D interconnects may be perpendicular or non-perpendicular to the even or odd numbered lines. The freedom of two-dimensional patterning compared to conventional self-aligned multiple patterning (SAMP) processes used in the 1-D patterning processes is provided. The two-dimensional patterning described herein provides line widths that match the critical dimensions in both x and y directions. The separation between the 1-D lines or between 2-D interconnects and the end of 1-D lines can be kept to a constant and at a minimum.

  • Publication number: 20180308749
    Abstract: The present disclosure describes methods which employ a patterning photolithography/etch operations to form self-aligned interconnects with multi-metal gap fill. For example, the method includes a first pattern structure and a second pattern structure formed over a dielectric layer. Each of the first and second pattern structures includes a pair of spacers, and a center portion between the pair of spacers. A first opening, self-aligned to a space between the first and second pattern structures, is formed in the dielectric layer. A first conductive material is deposited in the first opening. The center portion of the second pattern structure is removed to form a void above the dielectric layer and between the pair of spacers of the second pattern structure. A second opening, self-aligned to the void, is formed in the dielectric layer; and a second conductive material is deposited in the second opening.
