    摘要： Methods for fabricating alternating phase shift masks or reticles used in semiconductor optical lithography systems. The methods generally include forming a layer of phase shift mask material on a handle substrate and patterning the layer to define recessed phase shift windows. The patterned layer is transferred from the handle wafer to a mask blank. The depth of the phase shift windows is determined by the thickness of the layer of phase shift mask material and is independent of the patterning process. In particular, the depth of the phase shift windows is not dependent upon the etch rate uniformity of an etch process across a surface of a mask blank.

    摘要： A method for forming transistors with mutually-aligned double gates. The method includes the steps of (a) providing a wrap-around-gate transistor structure, wherein the wrap-around-gate transistor structure includes (i) semiconductor region, and (ii) a gate electrode region wrapping around the semiconductor region, wherein the gate electrode region is electrically insulated from the semiconductor region by a gate dielectric film; and (b) removing first and second portions of the wrap-around-gate transistor structure so as to form top and bottom gate electrodes from the gate electrode region, wherein the top and bottom gate electrodes are electrically disconnected from each other.

    摘要： A method for forming carbon nanotube field effect transistors, arrays of carbon nanotube field effect transistors, and device structures and arrays of device structures formed by the methods. The methods include forming a stacked structure including a gate electrode layer and catalyst pads each coupled electrically with a source/drain contact. The gate electrode layer is divided into multiple gate electrodes and at least one semiconducting carbon nanotube is synthesized by a chemical vapor deposition process on each of the catalyst pads. The completed device structure includes a gate electrode with a sidewall covered by a gate dielectric and at least one semiconducting carbon nanotube adjacent to the sidewall of the gate electrode. Source/drain contacts are electrically coupled with opposite ends of the semiconducting carbon nanotube to complete the device structure. Multiple device structures may be configured either as a memory circuit or as a logic circuit.

    摘要： A method for fabricating a metal-oxide-semiconductor device structure. The method includes introducing a dopant species concurrently into a semiconductor active layer that overlies an insulating layer and a gate electrode overlying the semiconductor active layer by ion implantation. The thickness of the semiconductor active layer, the thickness of the gate electrode, and the kinetic energy of the dopant species are chosen such that the projected range of the dopant species in the semiconductor active layer and insulating layer lies within the insulating layer and a projected range of the dopant species in the gate electrode lies within the gate electrode. As a result, the semiconductor active layer and the gate electrode may be doped simultaneously during a single ion implantation and without the necessity of an additional implant mask.
