Abstract:
Methods of manufacturing a complementary metal oxide semiconductor (CMOS) image sensor, include forming, in a semiconductor substrate, at least one device isolation layer defining an active area; forming at least one gate dielectric layer on the active area; forming at least one gate on the active area and the at least one device isolation layer, wherein first conductive-type impurity ions are injected into the at least one gate; and injecting second conductive-type impurity ions into portions of the at least one gate arranged on the at least one device isolation layer and edges of the active area adjacent to the at least one device isolation layer.
Abstract:
A medical device diagnostic apparatus and a control method thereof are provided. The medical device diagnostic apparatus includes a communicator connected to a controlled medical device, the communicator being configured to transmit and receive data to and from the controlled medical device, and a controller configured to select a component from components of the controlled medical device based on the received data, calculate a difference value between input and output data of the selected component and input and output data corresponding to the selected component in reference data, determine whether the difference value is greater than a value, determine that the selected component operates abnormally in response to the controller determining that difference value is greater than the value, and select another component from the components in response to the controller determining that the difference value is less than or equal to the value.
Abstract:
An electronic device according to an embodiment may comprise: a speaker, an amplifier connected to the speaker through a first electrical path; and at least one processor electrically connected to the amplifier, wherein the at least one processor is configured to: provide a first audio signal set to a first volume level to the speaker via the amplifier; when the first volume level is less than a predetermined first value, output the first audio signal at the first volume level through the speaker; and when the first volume level is equal to or greater than the first value, control a volume level of the first audio signal on the basis of a temperature value of the speaker, which is estimated from the first audio signal.
