  • Publication number: 20250153273
    Abstract: A wafer processing apparatus may include a light source unit emitting a first beam, a first spatial laser modulator reflecting the first beam, a beam expander adjusting a divergence angle of the first beam, a sensor unit emitting a second beam, a second spatial laser modulator reflecting the second beam, a galvanometer reflecting the first beam or the second beam, and a condensing lens refracting the first beam or the second beam. The sensor unit may receive position information generated while the second beam is moving in a first direction on a wafer. The first beam may be condensed to a condensing point by the condensing lens. Angle information for controlling a height level of the condensing point may be generated based on the position information. The beam expander may adjust the divergence angle of the first beam based on the angle information.

  • Patent number: 11698572
    Abstract: The present invention relates to a device for controlling a multi-axial point tilt of a camera lens and a method therefor, characterized by controlling a camera lens to move within a common stroke section among respective stroke sections in which the camera lens can move in an axis direction (z-axis) parallel to an optical axis direction at each of three or more axial points, wherein the camera lens is moved to a target position by using a compensation factor that is compensated such that a lens movement distance for each control code is the same.

  • Patent number: 11483303
    Abstract: Provided are a blockchain-based one ID service system and method, in an authentication method according to the embodiment of present invention, an authentication support server maps and registers a first ID issued by a first SP server to a first user and a first site of the first SP server, which is an issuing server, and, upon receiving the first ID from a second SP server, the authentication support server returns information on the first site mapped to the first ID to the second SP server. To this end, there is no need for a separate server configuration to perform an authentication procedure, and it is possible to lessen the burden of performing authentication for SPs.
