摘要： A method for forming a gate for a FinFET uses a series of selectively deposited sidewalls along with other sacrificial layers to create a cavity in which a gate can be accurately and reliably formed. This technique avoids long directional etching steps to form critical dimensions of the gate that have contributed to the difficulty of forming FinFETs using conventional techniques. In particular, a sacrificial seed layer, from which sidewalls can be accurately grown, is first deposited over a silicon fin. Once the sacrificial seed layer is etched away, the sidewalls can be surrounded by another disposable layer. Etching away the sidewalls will result in cavities being formed that straddle the fin, and gate conductor material can then be deposited within these cavities. Thus, the height and thickness of the resulting FinFET gate can be accurately controlled by avoiding a long direction etch down the entire height of the fin.

摘要： Methods for selecting semiconducting carbon nanotubes from a random collection of conducting and semiconducting carbon nanotubes synthesized on multiple synthesis sites carried by a substrate and structures formed thereby. After an initial growth stage, synthesis sites bearing conducting carbon nanotubes are altered to discontinue synthesis at these specific synthesis sites and, thereby, halt lengthening of the conducting carbon nanotubes. Synthesis sites bearing semiconducting carbon nanotubes are unaffected by the alteration so that semiconducting carbon nanotubes may be lengthened to a greater length than the conducting carbon nanotubes.

摘要： A method for synthesizing carbon nanotubes and structure formed thereby. The method includes forming carbon nanotubes on a plurality of synthesis sites supported by a first substrate, interrupting nanotube synthesis, mounting a free end of each carbon nanotube to a second substrate, and removing the first substrate. Each carbon nanotube is capped by one of the synthesis sites, to which growth reactants have ready access. As the carbon nanotubes lengthen during resumed nanotube synthesis, access to the synthesis sites remains unoccluded.

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 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.
