摘要:
A method is provided involving the growth of carbon nanotubes to provide giant resistance anisotropy or a low-k dielectric. The method comprises growing a plurality of one-dimensional nanostructures (18) orthogonal to a first conductive layer (14). A dielectric material (22, 32, 60) is formed covering the plurality of one-dimensional nanostructures and then etched to remove a portion of the dielectric material (22, 32, 60) to expose the ends (24, 34, 68) of the one-dimensional nanostructures (18). A second conductive layer (26, 36, 84) is formed over the dielectric material (22, 32, 60) to make contact with the ends (24, 34, 68) of the one-dimensional nanostructures (18). One or both of the first (14) and second (26, 36, 84) layers may be patterned for accessing individual or groups of the one-dimensional nanostructures (18). In another exemplary embodiment, the one-dimensional nanostructures (18) may be removed prior to forming the second layer (84), thereby creating a high-k dielectric layer (32) between the first and second layers (14, 84).

A method for preparing a semiconductor substrate surface (28) for semiconductor device fabrication, includes providing a semiconductor substrate (20) having a pure Ge surface layer (28) or a Ge-containing surface layer (12), such as SiGe. The semiconductor substrate (20) is cleaned using a first oxygen plasma process (14) to remove foreign matter (30) from the surface (28) of the substrate (20). The substrate surface (28) is next immersed in a hydrochloric acid solution (16) to remove additional foreign matter (30) from the surface (28) of the substrate (20). The immersion step is followed by a second oxygen plasma etch process (18), passivate the surface with a passivation layer (34), and provide for an atomically smooth surface for subsequent epitaxial or gate dielectric growth.

A transparent force sensor for use in touch panel displays (touch screens) and method for fabricating the same are disclosed. The transparent force sensor is capable of detecting touch by measuring local pressure applied by a touch input to a display area of the touch screen.
摘要:
A device and method eliminates a shadowing effect on a touch input receiving device. The method includes receiving a touch input on a top layer that includes first conducting lines, a first current passing through the first conducting lines. The method includes determining a location of the touch input as a function of the first current passing through an intermediate layer as a second current to second conducting lines orthogonal to the first conducting lines of a bottom layer. The intermediate layer disposed between the top and bottom sides is configured as a resistive layer applying a resistance value to the first current upon the touch input being received. The first current continues through the first conducting lines along a remainder thereof as a third current after passing through the intermediate layer to eliminate the shadowing effect.
摘要:
A system for displaying the listings of files and/or folders in one of a plurality of different views (e.g., gallery view or list view). In particular embodiments, the system determines which of the views to display in the listings in based on: (1) the types of files to be displayed; (2) a specified preference of a content sharer; and/or (3) a specified preference of a content recipient. Various embodiments are particularly useful for displaying lists of files that a content sharer shares with a content recipient via a URL within the context of a synched file sharing system.
