摘要： In making a vertical bipolar transistors, after forming by diffusion process a region to become inactive base region an oxide film is selectively formed on the region, thereafter an ion implantation is carried out to produce regions which become the active base region and emitter region by using the oxide film; thereby such a configuration is formed so that defect part (108) induced at the time of the ion implantation is confined in the emitter region, thereby minimizing the leakage current at the PN junction, and hence assuring production of high performance and high reliability semiconductor devices; further, a high integration is attained by adopting self-alignment in forming emitter contact.

摘要： In a tone control circuit of luminance signals, an adjusting current is used to add to or subtract from input signals with a gain control. Output signals are thus controlled to have a predetermined gradient based on an arbitrary output setting voltage against the input signals, and an input-output characteristic represented by an arbitrary line graph is obtained by plural gradient adjusting circuits.

摘要： A tone correction circuit for a luminance signal which can provide several shapes of correction characteristics. The tone correction circuit comprises a circuit in which the current increases at a first specified voltage or higher and decreases at a second specified voltage or higher so that the current is outputted in a specified range and also provided is a circuit which serves to increase the current at the second specified voltage or higher. Thus, without changing the output voltage at the midpoint, the correction amounts at the minimum point and midpoint, the shifting amount of the midpoint, the correction amounts from to the maximum point and the correction amount at the maximum point, can be controlled so that an optimum output waveform can be obtained in accordance with a scene, and particularly, fuzzy control for the scene can be efficiently made.

摘要： A black compensation circuit for compensating a luminance signal which is subjected to edge enhancement, comprises: a black-level expanding circuit responsive to a control signal including an edge enhancement component and the luminance signal for performing expansion of a tone of a black portion of the luminance signal and for performing conversion of the luminance signal into a black-level expanded signal in the absence of the control signal; a low-pass filter circuit for low-pass filtering the luminance signal to remove the edge enhancement component; a detection circuit responsive to an output of the low-pass filter circuit for detecting the blackest level for a given interval; and a comparing circuit for comparing the blackest level with a given level to produce the control signal, the black-level expanding circuit stopping the expansion and the conversion in the presence of the control signal. The blackest level does not change with sharpness because after the luminance signal subjected to edge enhancement is passed through the low-pass filter, it is sent to the detection circuit. An input signal of the low-pass filter may be supplied from the black-level expanding circuit.

摘要： A semiconductor integrated circuit arrangement prevents the occurrence of latch up. The circuit includes a first semiconductor island of a first conductivity type and a second semiconductor island of the first conductivity type located within a base semiconductor region of a second conductivity type. A resistive diffusion region of the second conductivity type is located within the first semiconductor island region. The second semiconductor region is connected to ground. A high potential electrode connected to the resistive diffusion region is also connected to the first semiconductor island region. In this manner, an emitter and a base of a parasitic transistor of the integrated circuit are connected together to prevent the parasitic transistor from operating in a conductive state, thereby preventing latch up.

摘要： The average picture level (APL) of a video luminance signal is detected, wherein the output of a first current mirror circuit used as the load of a differential amplifying circuit is fed into a smoothing circuit via a second current mirror circuit. The direct current voltage of the output and the detection voltage amplitude may be optionally set without causing an offset voltage in the output average picture level voltage, with the current flowing through the second current mirror circuit being made zero at the time of APL=0%.
