Abstract:
There is provided a bipolar transistor (with a respective fabrication method) that provides superior noise characteristics and gain diffusion. The fabricating method includes forming a first base region at a collector region, which in turn is formed on a substrate. A first silicon layer is formed on the base region, and a second silicon layer is formed on the first silicon layer using a forming method different from the method used in forming the first silicon layer. An emitter region is then formed from impurities at the base region by performing a thermal process.

Abstract:
A system for sensing an alarm indicating a failure happening on a trunk in an Asynchronous Transfer Mode (ATM) network. In the system, upon failure to receive an alarm indicating a failure occurrence on the trunk, a base station controller (BSC) determines whether a Loss of Cell Delineation (LCD) alarm happens due to a failure to normally receive data through the trunk. A failure manager manages a failure according to a report on the LCD alarm, received from the BSC. A base station transceiver subsystem (BTS), if it perceives a failure has happened on the trunk, informs the failure manager of the occurrence of the LCD alarm.
