Abstract: There is provided an overlay measurement device controlling a focus movement, which includes: a lighting part being configured to orient lighting toward an overlay measurement target; a collection part comprising an objective lens and a detector for obtaining one or more of images of each focus in the overlay measurement target; a lens focus actuator moving the objective lens to adjust a distance between the objective lens and a wafer; and a processor controlling an operation of the lens focus actuator. The processor obtains a focus graph respectively in relation to two layers from one or more of the images of each focus, and the processor identifies a reference focus in relation to the obtained focus graphs to move the objective lens.

Abstract: An antiferroelectric and a method for manufacturing an antiferroelectric are disclosed herein. The antiferroelectric may have high permittivity and breakdown voltage by having a PbxLa1-x([Zr1-YSnY]ZTi1-Z) composition. The manufacturing of the antiferroelectric may be performed through appropriate mixing and dysprosium addition.

Abstract: A method of reinforcement learning of a neural network device for generating a verification vector for verifying a circuit design comprising a circuit block includes inputting a test vector to the circuit block, generating one or more rewards based on a coverage corresponding to the test vector, the coverage being determined based on a state transition of the circuit block based on the test vector, and applying the one or more rewards to a reinforcement learning.

Abstract: An electronic device includes a display device, which may be fabricated using a described method. The display device includes a glass substrate including a first surface, a second surface opposite the first surface, and a side surface between the first surface and the second surface, an outermost structure on the first surface of the glass substrate and located adjacent to an edge of one side of the glass substrate, and a display area including a plurality of light emitting areas on the first surface of the glass substrate and located farther from the edge of the one side of the glass substrate than the outermost structure is. A minimum distance from the side surface of the glass substrate to the outermost structure is equal to 130 ?m or less.

Abstract: A washing machine and a method for supplying water thereof are disclosed. The washing machine comprises a supply valve for supplying cold/warm water into a tub, a water level detection unit for detecting a water level in the tub, and a microcomputer for performing an intermittent water supply and a continuous water supply by controlling an amount of water supplied to the tub from the water supply valve via a detergent barrel, and for controlling water supply according to the water level in the tub detected by the water level detection unit. The intermittent and continuous water supply is performed in such a manner of supplying water and stopping the water supply, and water supply time is differently set for the primary and secondary intermittent water supply, so that the detergent can be smoothly supplied to the tub without remaining in the barrel.

Abstract: Method for controlling a washing machine having a drum of which rotation speed is adjustable, including a first step for rotating the drum at a first rotation speed set at control unit, a second step for detecting whether resonance occurs or not at the drum rotating at the first rotation speed, and a third step for changing the rotation speed of the drum if the resonance is detected at the drum.
