Abstract: A method for manufacturing a chip scale package (CSP) including a semiconductor chip and conductive bumps is disclosed. In the present invention, a flexible substrate is provided with a conductive pattern formed thereon. The substrate has a top surface and a bottom surface. Then, a first photosensitive resin pattern is formed over the top surface of the substrate. Next, the first photosensitive resin pattern is cured. Subsequently, a second photosensitive resin pattern is formed over the cured first photosensitive resin pattern. The second photosensitive resin pattern includes a slit comprising a bottom of the first photosensitive resin pattern and side walls of the second photosensitive resin pattern. With the present invention, the problem of burning of neighboring patterns as well as the problem of the overflow of the encapsulant can be overcome.

Abstract: Disclosed is a process for effecting liquid-phase hydrogenation of MAN to GBL in high conversion and high selectivity. The present invention provides an improved process of catalytic hydrogenation for converting MAN or SA to GBL in the liquid phase in the presence of a noble metal (palladium-molybdenum-nickel) catalyst supported on silica having a large surface area. The catalytic hydrogenation is conducted at a temperature of 150 to 250° C. and under a pressure of 50 to 150 kg/cm2.

Abstract: Disclosed is a liquid crystal display panel capable of being cut by a laser light. The liquid crystal display panel according to the present invention includes a substrate having a buffer layer between a conducting layer and an inner surface of the substrate, in which the buffer layer is disposed along a cutting line and spreads a crack and edges of the conducting layer is positioned in a region defined by the cutting line. Further, a method for manufacturing the liquid crystal display panel is disclosed, in which the liquid crystal display panel is machined by a laser cutter and a laser grinder.

Abstract: Apparatus and method of data backup using a video tape recorder (VTR) where a backup composite video signal is generated by adding horizontal and vertical synchronous signals to digital data received from a host computer via a communication port, the backup composite video signal or an actual composite video signal input via an input connector of the VTR is selectively switched and input/output in accordance with a selection control signal, and the switched input is recorded/reproduced onto/from the video tape in accordance with a predetermined magnetic recording/reproducing method, thereby integrating data backup function and the unique function of the VTR. An operation mode of the VTR is switched in accordance with commands from the host computer. In addition, a luminance signal is frequency modulated to the frequency band extended up to those for a chrominance signal so that further more amount of backup data can be recorded onto the video tape.
