    Abstract: An on-chip memory cell comprises a tri-gate access transistor (145) and a tri-gate capacitor (155). The on-chip memory cell may be an embedded DRAM on a three-dimensional tri-gate transistor and capacitor structures which is fully compatible with existing tri-gate logic transistor fabrication process. Embodiments of the invention use the high fin aspect ratio and inherently superior surface area of the tri-gate transistors to replace the “trench” capacitor in a commodity DRAM with an inversion mode tri-gate capacitor. The tall sidewalls of the tri-gate transistor provide large enough surface area to provide storage capacitance in a small cell area.

    Abstract: Methods for uniformly tip doping a silicon body of a non-planar transistor and devices and systems formed by such methods. In one embodiment, a method can include vertical tip ion implantation of a silicon body with at least three surfaces on a substrate followed by conformal deposition of a dielectric material. The dielectric material can be selectively etched to expose a top surface of the silicon body followed by selective re-oxidation of the top surface for form a mask. The remaining dielectric material can be removed followed by angled ion implantation of at least two sidewalls of the silicon body. The mask can be removed resulting in a silicon body with uniform doping.
