20080211369 | Remote control lighting assembly and use thereof - A remote-controllable lighting device comprising a first substrate and an adjacent second substrate maintained in a spaced apart relationship to allow airflow therebetween and at least partly overlapping each other, at least the second substrates carrying thereon at least one emission sources, the first substrate being located towards a proximal end of the device and the second substrate being located towards a distal end of the device; said first substrate being arranged so as to allow light generated by the at least one located second light emission source to pass thereby in a direction defining a primary light emission direction and said first light emission source located so as to emit light in said primary light emission direction; said first and second substrate being in thermal communication so as to allow heat generated by the at least one light emission sources to flow between the substrates so as to provide thermal distribution between the substrates, the first and second substrate being formed of a thermally conductive material suitable for convection of the generated heat therefrom; a signal detector for receiving a wirelessly transmitted control signal from a remote control device; said signal receiver being located proximal of the first substrate in the primary light emission direction; and a controller in communication with said signal detector and the light emission sources and for controlling at least one characteristic of at least one light emission source responsive to said control signal. | 09-04-2008 |
20080199653 | Method of forming two-dimensional pattern by using nanospheres - The present invention relates to a method of forming a two-dimensional pattern, which includes: dispersing a plurality of spheres on a substrate; using the spheres to form a mask on the substrate; etching the substrate; and removing the mask from the substrate. In addition, the present invention further relates to a method of processing a surface of a substrate, which includes: dispersing a plurality of spheres on the surface of the substrate; depositing a substance among the spheres; and removing the spheres to leave the deposited substance on the surface of the substrate. The method of the present invention achieves a quicker and simpler process with a lower cost. In addition, a light emitting device manufactured through the method of the present invention has preferred light extraction efficiency and a variable radiation field pattern. | 08-21-2008 |
20080197367 | Method of super flat chemical mechanical polishing technology and semiconductor elements produced thereof - The present invention provides a method of super flat chemical mechanical polishing (SF-CMP) technology, which is a method characterized in replacing laser lift-off in a semiconductor fabricating process. SF-CMP has a main step of planting a plurality of polishing stop points before polishing the surface, which is characterized by hardness of the polishing stop points material being larger than hardness of the surface material. Therefore, the present method can achieve super flat polishing surface without removing polishing stop points. | 08-21-2008 |
