The patent describes a single location and application on a network where a user can organize public, group, and private/personal information and have this single, location accessible to the public. A new, ontology-driven portal that organizes all three categories of data according to various “facets” using underlying ontologies to define each “facet” and wherein any type of information can be classified and linked to other types of information is disclosed. An application that enables a user to effectively utilize and manage knowledge and data the user posses and allows other users to effectively and seamlessly benefit from the user's knowledge and data over a computer network is also disclosed. A method of processing content created by a user utilizing a semantic, ontology-driven portal on a computer network is described. The semantic portal application provides the user with a content base, such as a semantic form or meta-form, for creating a semantic posting. The semantic portal utilizes a knowledge data structure, such as a taxonomy or ontology, in preparing a semantic posting based on the information provided by the user via the content base. The semantic portal application prepares a preview of a semantic posting for evaluation by the user. The semantic posting is then either modified by the user or accepted and posted by the user for external parties to view.

The present invention provides structures and methods for a transistor formed on a V-shaped groove. The V-shaped groove contains two crystallographic facets joined by a ridge. The facets have different crystallographic orientations than what a semiconductor substrate normally provides such as the substrate orientation or orientations orthogonal to the substrate orientation. Unlike the prior art, the V-shaped groove is formed self-aligned to the shallow trench isolation, eliminating the need to precisely align the V-shaped grooves with lithographic means. The electrical properties of the new facets, specifically, the enhanced carrier mobility, are utilized to enhance the performance of transistors. In a transistor with a channel on the facets that are joined to form a V-shaped profile, the current flows in the direction of the ridge joining the facets avoiding any inflection in the direction of the current.

The epitaxial film is deposited into the predetermined regions of the substrate wherein the substrate has a temperature between about 350° C. and about 900° C. when the epitaxial film is being deposited.

An example system and method elicits reviews and opinions from users via an online system or a web crawl. Opinions on topics are processed in real time to determine orientation. Each topic is analyzed sentence by sentence to find a central tendency of user orientation toward a given topic. Automatic topic orientation is used to provide a common comparable rating value between reviewers and potentially other systems on similar topics. Facets of the topics are extracted via a submission/acquisition process to determine the key variables of interest for users.

The trench has a facet passing through the three-dimensional device a predetermined offset from a desired image position. The method further comprises iteratively, until a remaining distance between the facet and the desired image position is less than a predetermined threshold, adjusting one or more parameters of a polishing beam based on the remaining distance, polishing the facet with the polishing beam to position the facet closer to the desired image position, and measuring the remaining distance.

A structural shape on the surface of an optical substrate is such that the brightness of diffuse light departing from the surface of the optical substrate at certain off axis angles is reduced, at the expense of a small reduction in peak brightness measured near the viewing axis. The net result is an overall increase in useful illumination. A cross section of a prism as the structural shape has a curved sidewall or facet. A material with a relatively high index of refraction combined with a prismatic structure having a modified prism geometry improves brightness.

A backlight apparatus has a collimating waveguide with a light input end, a top surface, a bottom surface, opposing sides, a far end opposite the light input end, and a total internal reflection critical angle for the material of the waveguide. A plurality of first facets are formed in the bottom surface distributed along the waveguide between the light input end and the far end. Each of the first facets has a first facet bottom surface which converges toward the top surface in a direction away from the far end relative to the top surface. A light scattering and reflective surface is disposed adjacent the far end of the collimating waveguide. The first facet bottom surfaces cause light rays entering the light input end to be totally internally reflected to the far end of the collimating waveguide wherein the scattering and reflective surface at the far end reflects and scatters light rays incident thereon back toward the light input end. The first facet bottom surfaces then cause the light rays reflected from the far end to exit the top surface. The first facet bottom surfaces may be formed either as straight facets or as curved surface facets and may also be alternatively formed having a reflective material layer thereon.
