    摘要: In general, in one aspect, a method includes forming a semiconductor fin. A first insulating layer is formed adjacent to the semiconductor fin. A second insulating layer is formed over the first insulating layer and the semiconductor fin. A first trench is formed in the second insulating layer and the first insulating layer therebelow. The first trench is filed with a polymer. A third insulating layer is formed over the polymer. A second trench is formed in the third insulating layer, wherein the second trench is above the first trench and extends laterally therefrom. The polymer is removed from the first trench. A capacitor is formed within the first and the second trenches.

    摘要: Recessed channel array transistor (RCAT) structures and method of formation are generally described. In one example, an electronic device includes a semiconductor substrate, a first fin coupled with the semiconductor substrate, the first fin comprising a first source region and a first drain region, and a first gate structure of a recessed channel array transistor (RCAT) formed in a first gate region disposed between the first source region and the first drain region, wherein the first gate structure is formed by removing a sacrificial gate structure to expose the first fin in the first gate region, recessing a channel structure into the first fin, and forming the first gate structure on the recessed channel structure.

    摘要: A semiconductor device comprising a semiconductor body having a top surface and a first and second laterally opposite sidewalls as formed on an insulating substrate is claimed. A gate dielectric is formed on the top surface of the semiconductor body and on the first and second laterally opposite sidewalls of the semiconductor body. A gate electrode is then formed on the gate dielectric on the top surface of the semiconductor body and adjacent to the gate dielectric on the first and second laterally opposite sidewalls of the semiconductor body. The gate electrode comprises a metal film formed directly adjacent to the gate dielectric layer. A pair of source and drain regions are then formed in the semiconductor body on opposite sides of the gate electrode.

    摘要: A method is described for forming an element of a microelectronic circuit. A sacrificial layer is formed on an upper surface of a support layer. The sacrificial layer is extremely thin and uniform. A height-defining layer is then formed on the sacrificial layer, whereafter the sacrificial layer is etched away so that a well-defined gap is left between an upper surface of the support layer and a lower surface of the height-defining layer. A monocrystalline semiconductor material is then selectively grown from a nucleation silicon site through the gap. The monocrystalline semiconductor material forms a monocrystalline layer having a thickness corresponding to the thickness of the original sacrificial layer.
