摘要:
A reactive ion etching technique is disclosed for etching a gate electrode out of layers of tungsten silicide and polycrystalline silicon without etching the underlying layer of silicon dioxide which serves as the gate dielectric and which covers the source and drain regions. The key feature of the invention, wherein the gate, which has been partially etched out of the tungsten silicide and polycrystalline silicon layers, is coated with poly tetra-fluoroethylene (teflon) to protect the sidewalls of the gate from being excessively etched in the lateral direction while the etching continues at the bottom on either side of the gate.The process is especially suitable for formation of tungsten silicide structures since no subsequent thermal steps are required which would otherwise cause a delamination of the tungsten silicide. In addition to eliminating undercutting, the process does not disturb the gate oxide over the source and drain areas, which would otherwise create a leaky device unsuitable for applications such as dynamic RAMs. The entire process can be carried out in a single pump down and therefore contamination levels can be minimized.

Systems, storage medium, and methods associated with adaptive visual output on a mobile device are disclosed herein. In embodiments, a storage medium may have instructions to enable the mobile device to determine a change in a distance between the mobile device and a user of the mobile device. The instruction may also enable the mobile device to operate an end-user application that may adaptively present a visual output based at least in part on a result of the change in the distance. Other embodiments may be disclosed or claimed.

System and techniques for enhanced imaging are described herein. Light from an environment may be sampled to create an image. Energy reflected from the environment may also be sampled to create a depth image of the environment. A classifier may be applied to both the image and the depth image to provide a set of object properties for an object in the environment. A composite image may be constructed that includes portions of the image and depth image representing the object as well as the object properties.

Methods and systems to predictively determine to perform a computing activity based on contextual information. Context-based criteria are defined based relationships between user-computing activity and contextual information, and are evaluated based on updated contextual information to determine whether to perform the computing activity. Context-based criteria may be defined to predictively identify content to be transferred/synchronized/updated and/or deleted, and/or to select one or more of multiple devices to receive content. Content may be selectively synchronized across devices of a user and/or shared with another user(s). Context-based criteria may relate to, without limitation, location, activity, computer-usage patterns, motion, and/or schedule of a user, device location, user/device proximity, relationships amongst content, users, and/or devices. Context-based computing environment parameters may be provided to pre-loaded content on device (e.g., store, open, and/or configure an operating system, application, and/or resource), with little or no user interaction.

In accordance with some embodiments of the present invention, information about a user's activities and habits may be collected on an ongoing basis with the user's permission. This information about previous history can then tied to inferences that enable predictions about the user's preferences. As a result, when it comes time for the user to make a decision or a selection, information about past history and permissible inferences can be used to automatically provide suggestions for implementing future activities. In addition, in some cases this previous history information can be used to optimize future selections.

Devices and methods for modifying content rendered on the display of a computing device as a function of eye focus area include receiving sensor data from one or more eye tracking sensors, determining an eye focus area on the display screen as a function of the sensor data, and adjusting one or more visual characteristics of the rendered content as a function of the eye focus area. Perceived quality of the rendered content may be improved by improving the visual characteristics of the content displayed within the eye focus area. Rendering efficiency may be improved by degrading the visual characteristics of the content displayed outside of the eye focus area. Adjustable visual characteristics include the level of detail used to render the content, the color saturation or brightness of the content, and rendering effects such as anti-aliasing, shading, anisotropic filtering, focusing, blurring, lighting, and/or shadowing.

摘要:
A process and structure for depositing metal lines in a lift-off process is disclosed. The process comprises the deposition of a four-layer structure or lift-off stencil, comprising a first layer of a lift-off polymer etchable in oxygen plasma, a first barrier layer of hexamethyldisilizane (HMDS) resistant to an oxygen plasma, a second lift-off layer and a second barrier layer. Once these layers are deposited, a layer of photoresist is deposited and lithographically defined with the metal conductor pattern desired. The layers are then sequentially etched with oxygen and CF.sub.4, resulting in a dual overhang lift-off structure. Metal is then deposited by evaporation or sputtering through the lift-off structure. Following metal deposition, the stencil is lifted-off in a solvent such as N-methylpyrrolidone (NMP).
