摘要： Disclosed are a heterojunction bipolar transistor and a method of fabricating the same. A first dielectric layer easily etched is deposited on the overall surface of a substrate before an isolation region is defined. The first dielectric layer and a sub-collector layer are selectively etched, and then a second dielectric layer etched at a low etch rate is deposited on the overall surface of the substrate. Via holes are formed in the first and second dielectric layers, and then the first dielectric layer is removed using a difference between etch characteristics of the first and second dielectric layers. Accordingly, a reduction in power gain, generated at the interface of a compound semiconductor and a dielectric insulating layer (the second dielectric layer), can be eliminated.

摘要： A display device includes a plurality of pixels arranged in matrix, a plurality of gate lines, a plurality of data lines, and a gate driver connected to the plurality of gate lines. The gate driver receives a first scan start signal, a second scan start signal and clock signals and outputs a gate-on voltage to each of the plurality of gate lines. The gate driver outputs the gate-on voltage to the plurality of gate lines such that the gate-on voltages do not overlap with each other when the gate driver receives the first scan start signal. The gate driver outputs the gate-on voltage to at least two of the gate lines at substantially the same time when the gate driver receives the second scan start signal.

摘要： The present invention relates to the information protection of digital content transferred by streaming and download service through wire or wireless Internet network. The information protection system in this invention suggests a drastic prevention method of copyrights infringement such as illegal copy and unauthorized distribution of digital content, by using of the encryption, decryption, distribution, and authentication technologies. This invention suggests the control technology of general viewer program, not the specific viewer program for information protection, using a network filter driver for streaming and file system filter driver for download service. The main function of network and file system filter driver is the filtering operation such as a hooking, changing, decrypting, and restoring of message and data packet, and transferring to the viewer program. The main idea and technology of this invention suggest higher secure and efficient digital information protection system for live/VOD/HTTP streaming and download service.
