Abstract:
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.
Abstract:
A portable karaoke device comprising an MP3 decoder for downloading an accompaniment of a desired tune, and an expandable sound module for storing the accompaniment downloaded by the MP3 decoder. A video signal is received from a video unit by radio and then utilized as a background picture. A video signal mixed with a lyrics caption is transmitted by radio to the video unit so that the user can view the background picture and lyrics. In addition to a main microphone over which the user sings while listening to an accompaniment sound, there is provided an auxiliary microphone for transmitting a signal by radio. The user can select and apply a next tune using the auxiliary microphone while singing over it. Therefore, with no necessity for replacing a sound module in which lyrics and accompaniments of newest songs are previously recorded and a video unit that provides a background picture, the user can simply and efficiently use the present device.
