    Abstract: Provided are a semiconductor laser diode and a method of manufacturing the same. The semiconductor laser diode includes a lower cladding layer disposed on a substrate; a ridge including an optical waveguide layer, an active layer, an upper cladding layer, and an ohmic contact layer, which are sequentially stacked on the lower cladding layer, and having a predetermined width, which is obtained by performing a channel etching process on both sides of the ridge; an oxide layer disposed on surfaces of the upper and lower cladding layer to control the width of the ridge; a dielectric layer disposed on left and right channels of the ridge; an upper electrode layer disposed on the entire surface of the resultant structure to enclose the ridge and the dielectric layer; and a lower electrode layer disposed on a bottom surface of the substrate. The method is simpler than a conventional process of manufacturing a semiconductor laser diode. Also, by controlling a wet oxidation time, the width of a ridge can be freely controlled and an ohmic contact layer can be automatically formed.

    Abstract: The present invention provides a process for using an amine contamination-protecting top-coating composition. Preferably, the amine contamination-protecting top-coating composition of the present invention comprises an amine contamination-protecting compound. Useful amine contamination-protecting compounds include amine derivatives; amino acid derivatives; amide derivatives; urethane derivatives; urea derivatives; salts thereof; and mixtures thereof. The amine contamination-protecting top-coating composition of the present invention reduces or eliminates problems such as T-topping due to a post exposure delay effect and/or difficulties in forming a fine pattern below 100 nm due to acid diffusion associated with conventional lithography processes involving a photoresist polymer containing an alicyclic main chain using a light source, such as KrF (248 nm), ArF (193 nm), F2 (157 nm), E-beam, ion beam and extremely ultraviolet (EUV).

    Abstract: A light guide plate and a liquid crystal display device having the same. The light guide plate is disposed upstream of a liquid crystal panel to refract light supplied through an edge thereof, toward the liquid crystal panel. In the light guide plate, a plate body is disposed at a side of a light source for supplying light when a supply voltage is applied. A plurality of pyramidal diffusing elements are arrayed in a predetermined pattern on a surface of the plate body. Each of the diffusing elements is rotated clockwise or counterclockwise about an axis extending through a vertex of the diffusing element perpendicularly to the surface of the plate body so that an edge of the diffusing element facing a reference line connecting a central point of the light source to a central point of the plate body is angled 10° to 35° about the reference line.

    Abstract: Conventional rechargeable battery packs for portable electronic products possess charging terminals for connecting the battery packs to charging devices. When a portable electronic product is in use, there is a potential for short circuiting the battery pack by connecting one or more objects to the exposed charging terminals. This invention provides a battery pack for a portable electronic product with a short circuit prevention function where the charging terminal is exposed only when plugged into a charging device. By protecting the charging terminals, the invention prevents a short circuit from occurring during normal operation of the portable electronic product. The battery pack with a short circuit prevention function comprises a spring-loaded cover that is adapted to travel over the main body of the battery pack to alternately cover and expose the charging terminal.
