Abstract: PURPOSE: A method for fabricating a heterojunction bipolar transistor is provided to realize an improvement in electrical characteristics, simplified processes, and increased reliability. CONSTITUTION: After a semi-insulated InGaP buffer layer is grown on a semi-insulated GaAs substrate(1), an n+ GaAs sub-collector layer, an n- GaAs collector layer, a p+ GaAs base layer, an N InGaP emitter layer, and an n+ GaAs emitter cap layer are formed thereon in sequence. Then, by using an emitter metal deposited on the emitter cap layer as a mask, the emitter cap layer and the emitter layer are selectively etched. Thereafter, a base metal is formed by lift-off to be self-aligned with the emitter metal. While emitter/base regions are covered with a resist layer, the base layer and the collector layer are etched to expose the sub-collector layer. Next, a collector metal is formed by lift-off and covered with a resist layer, and then the sub-collector layer is etched to electrically isolate individual devices. A pad metal(12) is then deposited on the exposed buffer layer and connected to the device with an air-bridge metal. Thereafter, a via hole(14) is formed in the substrate(1), and a ground pad is formed.

Abstract: PURPOSE: A method of changing an aspect ratio in an image receiving processor is provided to automatically change the aspect ratio from 16:9 to 4:3 when a teletext mode is set, thereby enabling a user to identify teletext character easily. CONSTITUTION: In an image receiving processor(7 ), an aspect ratio is set to 16:9 or 4:3 and a teletext character broadcasting is received. A general image signal is received in the image receiving processor and the image signal is displayed in an aspect ratio of 16:9. Whether a teletext mode for displaying a teletext character is selected is determined during displaying of the image signal. Then, the aspect ratio of 16:9 is changed into 4:3 to display the teletext character, if the teletext mode is selected. And, the aspect ratio of 4:3 is changed into 16:9 to display the image signal, if a mode for displaying the image signal is selected.

Abstract: PURPOSE: A method for detecting an error of an imaging element and for correcting the error is provided to make a micro computer constantly compare a vertical blanking signal generated from the element with a vertical blanking signal generated when the element is normally operated. According to a preset time, it is detected whether the operation of the element is wrong or not so as to quickly convert the wrongly-operated element into a normal operation state. CONSTITUTION: A micro computer initializes a horizontal/vertical processor(S100). An error flag(Error-Fg), an error check flag(ErrorCheck-Fg), and a vertical blanking time(V_BLK_Time) are set up as '0'. The micro computer decides whether the horizontal/vertical processor is driven(S200). If not, the micro computer returns to the step 'S200'. If the horizontal/vertical processor is driven, the micro computer sets up an error check state, to check a wrong operation of the horizontal/vertical processor(S300). The error check flag(ErrorCheck-Fg) is set up as '1'. The micro computer checks the wrong operation of the horizontal/vertical processor(S400). If the horizontal/vertical processor is not wrongly operated, the micro computer returns to the step 'S300'. If the horizontal/vertical processor is wrongly operated, the micro computer returns to the step 'S100'. When the horizontal/vertical processor is wrongly operated, the error flag(Error-Fg) is set up as '1'.

Abstract: PURPOSE: A destination call waiting method in a mobile communication terminal is provided to allow a calling party to listen to an announcement message to be in a waiting state, leave a voice or a character message or release a call by transmitting a previously recorded announcement message during a short response delay time period in case that a called party is not in a good situation to answer a phone call. CONSTITUTION: A controller is in a standby state for receiving a call(311). The controller determines whether a call is terminated(313). If a call is terminated, the controller determines whether a certain key is inputted from a key input unit(315). If no key is inputted, the controller transmits a ring signal informing of a call termination to a speaker, as a normal call termination process(317). If a key is inputted, the controller determines whether the inputted key is a waiting manner key(319). If the inputted key is not a waiting manner key, the controller determines whether the inputted key is a speech key(321). If the inputted is a speech key, the controller forms a speech path to the call origination party and proceeds to a call communication state(323). If the inputted key is a waiting manner key, the controller transmits a flash information message and transmits an announcement voice message indicating of setting of a destination call waiting function stored in a voice memory to the call origination party(325). The controller drives a waiting time timer according to the destination call waiting function(327). The controller determines whether a key requesting a call connection is inputted from the key input unit(329). If a key for requesting a call connection is not inputted, the controller determines whether the waiting time timer is completely driven(331). If the waiting time timer is completely driven, the controller transmits an excuse message stored in the voice memory and releases a call(333). If the call connection key is inputted, the controller resumes a delayed call(335). The controller determines whether a call release key is inputted from the key input unit(337). If the call release key is inputted, the controller releases the resumed call(339).
