Abstract: A semiconductor device includes active fins on a substrate, a first isolation pattern on the substrate, the first isolation pattern extending on a lower sidewall of each of the active fins, a third isolation pattern including an upper portion extending into the first isolation pattern and a lower portion extending into an upper portion of the substrate, the lower portion contacting the upper portion of the third isolation pattern, and having a lower surface with a width greater than that of an upper surface thereof, and a second isolation pattern extending in the substrate under the third isolation pattern, contacting the third isolation pattern, and having a rounded lower surface.
Abstract: Embodiments of this application disclose a communication method, an apparatus and a computer-readable storage medium. The method includes sending first request information to an access management network element, where the first request information carries an application capability of a terminal device. The method also includes receiving first response information sent by the access management network element. The method further includes sending a session establishment request to a session management network element based on the first response information, where the session establishment request requests to establish a connection to a first application network element. According to the technical solutions provided in this application, interaction signaling between a terminal device and a server can be reduced, and communication latency can be reduced.
Abstract: An image sensor includes a photodiode array having a plurality of photodiodes, a grid disposed over the photodiode array, and a plurality of optical components disposed over the grid and corresponding to the plurality of apertures, respectively. The grid defines a plurality of apertures corresponding to the plurality of photodiodes, respectively. The optical components includes a first optical component above a first photodiode of the plurality of photodiodes, the first optical component includes at least one lens and provides at least one focus on the first photodiode, in which the focus of the lens of the first optical component misaligns a center of the first photodiode, in a plan view.
Abstract: A cosmetic composition for peel-off-type packs includes a thickener so that pearl or powder particles are stabilized in a formulation to thus impart a sophisticated and differentiated appearance. The content of an alcohol ingredient therein is controlled to accelerate drying, which maximizes a lifting effect. Silicone, imparting a feeling of conditioning, is introduced into polyvinyl alcohol and polyvinyl pyrrolidone, which are film formers, thus minimizing skin irritation upon peeling off.

Abstract: A secondary battery management system, a secondary battery management method and a secondary battery management program for the secondary battery management system, and a secondary battery system with which a target state of charge of a secondary battery can be appropriately set by taking into consideration a degradation degree. A secondary battery management system includes a setting unit configured to set a temporary target state of charge of a secondary battery based on a target power amount, an estimating unit configured to estimate a degradation degree of the secondary battery based on an amount of change in a state of charge of the secondary battery over a predetermined constant-current charging period of the secondary battery, and a calculating unit configured to calculate a target state of charge of the secondary battery by correcting the temporary target state of charge in accordance with the degradation degree.
Abstract: A TV-Internet Integration Box allows display of first data broadcast over a TV subscriber channel simultaneously together with second data broadcast over a digital data communications network has respective first and second inputs for receiving at a user premises the first data and the second data according to a user-profile associated with the second data. A combiner unit combines the first data and second data to form a combined video signal; and a video output coupled to the combiner unit conveys the combined video signal to a TV set in a user premises for displaying a first image corresponding to the first data and having superimposed thereon a second image corresponding to the second data. A user at the user premises may interact with the second image for redirecting to the digital data communications network and displaying a program broadcast thereby in at least a portion of the TV set.
