Method of manufacturing a semiconductor device and the semiconductor device

The present invention provides a method of manufacturing a trench with a rounded corner portion and a broadened opening. Anisotropic oxidation is carried out using a halogen oxidation method using dichloroethylene (DCE) to form an anisotropic oxide film such that the film thickness in a shoulder portion of the trench is thick and gradually decreases nearer the bottom, the anisotropic oxide film is removed, and the shoulder portion of the trench is preferentially backed off, thereby rounding the shoulder portion sufficiently to broaden the opening. Then, an insulating member is embedded in the trench. The rounded portion of the shoulder portion of the trench and vicinity thereof is used as a channel of a MOS transistor.

IC substrate of glass and display device

Disclosed is an IC chip using a glass substrate capable of being manufactured at a lower cost than the IC chip using from a semiconductor wafer. Further, where the body substrate of a display device is made of glass, the IC chip and the body substrate can have equal coefficients of thermal expansion, thus preventing the IC chips from peeling off and reducing the failure rate. Furthermore, the gate line driving IC applied to a display device can be arranged as an IC chip having a length approximately equal to the display area, therefore, mounting a plurality of IC chips as the gate driving IC is not required, thereby reducing the production cost. Still further, all gate lines can be extended in parallel from the IC chip so that no difference in the delay occurs among the gate lines and the size of frame of display device can reduced.

Socket-welded pipe joint

A welded pipe joint having reduced internal stresses comprises a pipe, a socket fitting, and an annular weld. The end surface of the fitting is chamfered in a concave profile, so that the weld profile subtends an angle of from about 100 degrees to about 120 degrees, rather than the customary 90 degrees. The fitting and the pipe are welded together by applying, from outside the pipe, an annulus of added bead metal to the chamfered end surface of the fitting so as to surround the chamfered end surface, and fusing the base metal of the annular wall and pipe. The pipe has no dam or other protuberance to confine the bead of added metal. Prior to welding, the fitting may have an annular lip immediately surrounding the surface of the pipe and may also have a ring spaced from the lip. The ring may be integral with the fitting and spaced from the lip by thin, radially spaced metal bars or may be separate from the fitting.

Location Determination Using A Companion Device

Methods, systems, and computer program products for a mobile device determining its location based on a location of a companion device are described. A mobile device can receive a request for determining a location of the mobile device from an application. The request can include an accuracy specification providing a lower limit on accuracy of the determined location. The mobile device can determine that the mobile device is incapable of achieving that accuracy. The mobile device can then submit a location request to a companion device that has paired with the mobile device. The companion device, upon receiving the location request, can determine a location of the companion device and provide the location of the companion device to the mobile device. The mobile device can then designate the location of the companion device as the location of the mobile device, and provide the location to the application.
