A first insulating layer is formed on semiconductor substrate, and a trench is formed in the first insulating layer. An amorphous silicon layer doped with impurities is formed on a side and bottom walls of the trench. Next, a resist material is partially filled in the trench so that an upper portion of the amorphous silicon layer is exposed. The exposed portion is implanted with impurity ions. After removal of the resist material, the amorphous silicon layer is heat treated so as to grow hemispherical grains on its surface.

A tread (14) of a tire (10) includes a tread rubber layer (16). The tread rubber layer (16) has a two-layer structure including a base layer (23) and a cap layer (24). The base layer (23) is provided with a comb-shaped convex portion (26). The convex portion (26) is formed like a circle extended in the circumferential direction of the tire (10). A plurality of convex portions (26) is arranged in the axial direction of the tire (10) and is protruded in a radial direction. At least a part of the convex portions (26) is exposed to a tread surface (17) when the tire (10) is unused (brand-new). The cap layer (24) contains silica and the base layer (23) does not contain the silica.

An object of the present invention is to provide a technique for forming an ohmic connection between a semiconductor and a metal efficiently in a short period of time. The present invention provides a method of forming at least one electrode on a surface of a semiconductor, wherein a metal or alloy for the electrode is rubbed against a predetermined region of the semiconductor surface so as to be adhered by frictional force and frictional heat to the predetermined region of the semiconductor as an electrode and part of the adhered metal or a metal of the alloy is diffused into an inside of the semiconductor by the frictional heat thereby to be formed into an ohmic electrode substantially simultaneously when the metal or alloy is adhered by the frictional force and frictional heat to the predetermined region of the semiconductor.

First and second transistors are formed on the principal surface of the semiconductor substrate, and an insulating film is formed over the principal surface of the semiconductor substrate so as to cover the first and second transistors. A first storage node is connected to the first transistor and has a first enclosed wall structure which is formed over the insulating film and encloses a surface region of the insulating film. A second storage node is connected to the second transistor and has second enclosed wall structure which is formed over the insulating film and surrounds the first enclosed wall structure. A capacitor insulating film covers the first and second enclosed wall structures, and a cell-plate is formed on the capacitor insulating film.

摘要:
A local network node, connected to a remote network node by an active transmission system and a standby transmission system, includes an active receiver for receiving communication signals from the active transmission system and detecting an operating state of the active transmission system. An active transmitter transmits communication signals over the active transmission system to the remote network node. A standby receiver receives, from the standby transmission system, a status signal indicating an operating state of the active transmission system detected by the remote network node. A standby transmitter transmits a status signal indicating the operating state detected by the active receive circuitry over the standby transmission system to the remote network node. A control circuit is responsive to an operating state detected by the active receiver and an operating state indicated by the status signal of the standby receiver for performing a protection switching between the active and standby transmission systems.

A pneumatic radial tire comprises a carcass comprising an inner and outer plies, a belt comprising at least one ply of cords laid at an angle of from 0 to 35 degrees with respect to the tire circumferential direction, and a rubber bead apex disposed in each bead portion. The outer carcass ply comprises a main portion extending continuously between the bead portions, and a pair of turnup portions each turned up around a bead core from the axially inside to outside of the tire. The inner carcass ply is disposed inside and adjacent to the main portion and extending at least from the tread portion to the bead portions. The inner carcass ply is not wrapped around the bead core, and the radially inner end thereof is located radially inward of the radial outer end of the bead apex.
