The present invention provides to a gallium nitride (GaN) semiconductor and a method of manufacturing the same, capable of reducing crystal defects caused by a difference in lattice parameters, and minimizing internal residual stress. In particular, since a high-quality GaN thin film is formed on a silicon wafer, manufacturing costs can be reduced by securing high-quality wafers with a large diameter at a low price, and applicability to a variety of devices and circuit can also be improved.

Provided is a high voltage transistor in a flash memory device comprising: a source/drain junction of a DDD structure consisting of a high-concentration impurity region and a low-concentration impurity region surrounding the high-concentration impurity region, the high-concentration impurity region being formed in parallel with a gate electrode at a distance spaced by a location in which a contact hole is formed, and having a rectangular shape whose width is the same as or wider than that of the contact hole and whose length is the same as or narrower than that of an active region through which the gate electrode passes. Accordingly, a current density to pass the gate electrode neighboring the contact hole portion and a current density to pass the gate electrode at a portion where the contact hole cannot be formed become uniform. A uniform and constant saturation current can be obtained regardless of the number of the contact hole.

The present invention relates to an optical waveguide having a curved reflecting mirror surface for optical coupling and a method of manufacturing it. The method of manufacturing an optical waveguide includes the steps of coating a transparent glass substrate with a photosensitive material; radiating ultraviolet rays onto the photosensitive material through a mask in which the shape of the optical waveguide and partition blocks formed beside ends of the optical waveguide are patterned; manufacturing a photoresist stamp by developing patterns onto which the ultraviolet ray has been radiated through the mask; forming a PolyDiMethylSiloxane (PDMS) mold by coating the photo stamp with PDMS, and forming a core; forming the optical waveguide, in which the partition blocks are formed beside the ends thereof, using the PDMS mold; and dropping liquid polymer between the partition blocks formed beside the ends of the optical waveguide using an inkjet header and hardening it. This structure and manufacturing method have advantage in that optical waveguides having variously shaped reflecting mirror surfaces are simply and economically manufactured.

A method of manufacturing an LED package. The method includes dispensing a transparent resilient resin on an LED package body and overturning an entire structure to form an LED lens integrally provided to the LED package body. This prevents extra processes and costs incurring from forming intermediate layers and obviates degradation in reliability and light extraction efficiency due to additional interfaces.

Disclosed is a method of manufacturing rear plate barrier ribs for Plasma Display Panel (PDP), which includes the steps of: forming barrier ribs by infiltrating the barrier rib forming paste into grooves of a mold by using the capillary phenomenon, and then sintering the paste. This method causes rare environmental pollution, enables to make barrier ribs having fine and complex shapes and reduces material costs required for the barrier rib. Thus, the method may improve quality of PDP and reduce manufacture costs of the rear plate.

Disclosed is a method of manufacturing barrier ribs for a Plasma Display Panel (PDP), which includes the steps of forming a thick film (or, “green tape”) for barrier ribs on a glass or metal substrate by using composition for forming the barrier ribs, which contains water soluble components and solvent soluble components together a binder; forming a protective pattern film partially soluble or insoluble to the water based solution on the thick film; etching the thick film into a barrier rib shape by using solution or mixed solution containing ceramic powder as an etching accelerator, and sintering the etched thick film. This method causes rare environmental pollution, enables to make barrier ribs having fine and complex shapes and reduces material costs required for the barrier rib. Thus, the method may improve quality of DPD and reduce manufacture costs of the rear plate.
