    摘要: Provided is a method of fabricating a heterojunction bipolar transistor (HBT). The method includes: sequentially depositing a sub-collector layer, a collector layer, a base layer, an emitter layer, and an emitter capping layer on a substrate; forming an emitter electrode on the emitter capping layer; forming a mesa type emitter to expose the base layer by sequentially etching the emitter capping layer and the emitter layer using the emitter electrode as an etch mask in vertical and negative-sloped directions to the substrate, respectively; and forming a base electrode on the exposed base layer using the emitter electrode as a mask in self-alignment with the emitter electrode. In this method, a distance between the mesa type emitter and the base electrode can be minimized and reproducibly controlled. Also, a self-aligned device with an excellent high-frequency characteristic can be embodied.

    摘要: The present invention provides a diagnostic apparatus using a microphone. More specifically, the diagnostic apparatus utilizes a first microphone, a second microphone, a first unit, a controller and second unit. The first microphone is positioned within an engine compartment and the second microphone is positioned within an interior of a vehicle to receive the noise. The second unit records the noise inputted through the first microphone or the second microphone or both and the controller analyzes and diagnoses a vehicle utilizing the noise recorded by the first unit to determine if a failure in the vehicle has occurred. When a vehicle failure is detected by the controller, the second unit then notifies a user of the location of a failed part in the vehicle.

    摘要: A method for preparing a ZnO nanocrystal directly on a silicon substrate includes the steps of: (S1) forming a Zn—Si—O composite thin film on the silicon substrate; and (S2) thermally treating the obtained thin film. Particularly, ZnO nanocrystals are formed in an amorphous Zn—Si—O composite thin film by controlling the composition of the Zn—Si—O composite thin film and heating temperature thereof. With the present invention method for preparing a ZnO nanocrystal directly on a silicon substrate, more possibilities are opened up for the applications of ZnO nanocrystals to an optoelectronic device in use of a silicon substrate.
