20090087994 | METHOD OF FORMING FINE PATTERNS AND MANUFACTURING SEMICONDUCTOR LIGHT EMITTING DEVICE USING THE SAME - A method of forming a fine pattern begins with providing a c-plane hexagonal semiconductor crystal. A mask having a predetermined pattern is formed on the semiconductor crystal. The semiconductor crystal is dry-etched by using the mask to form a first fine pattern on the semiconductor crystal. The semiconductor crystal including the first fine pattern is wet-etched to expand the first fine pattern in a horizontal direction to form a second fine pattern. The second fine pattern obtained in the wet-etching the semiconductor crystal has a bottom surface and a sidewall that have unique crystal planes, respectively. The present fine-pattern forming process can be advantageously applied to a semiconductor light emitting device, particularly, to a phonic crystal structure required to have fine patterns or a structure using a surface plasmon resonance principle. | 04-02-2009 |

20090318655 | POLYCARBOSILANE AND METHOD OF PRODUCING THE SAME - Provided are polycarbosilane and a method of producing the same. The polycarbosilane contains an allyl group, and thus can be cured by UV absorption when not exposed to the air. | 12-24-2009 |
20130253119 | HIGH STRENGTH ORGANIC/INORGANIC COMPOSITE USING PLATE-SHAPED INORGANIC PARTICLES AND METHOD FOR PREPARING SAME - The present invention relates to a high strength organic/inorganic composite using plate-shaped inorganic particles and to a method for preparing the same. The organic/inorganic composite of the present invention comprises a polymer and inorganic particles uniformly arranged into a matrix structure in said polymer. A mineral bridge is formed between the inorganic particles. According to the present invention, plate-shaped inorganic particles are uniformly distributed in the polymer to improve the filling rate of inorganic particles, and a mineral bridge is formed between the inorganic particles to provide a high strength and lightweight organic/inorganic composite. The organic/inorganic composite of the present invention may be widely used in high value-added industry such as an aerospace industry, space industry, car industry, energy industry, environmental industry, defense industry and construction industry. | 09-26-2013 |
