Abstract: The application is related to a laser transfer apparatus and a method performed by the laser transfer apparatus. The laser transfer apparatus may include: a laser oscillator configured to perform irradiation with a laser beam; a first stage movably disposed below the laser oscillator; a second stage movably disposed below the first stage; a flatness measurement sensor; and a controller. The controller may be configured to control, once a transfer substrate on which a plurality of light emitting diodes (LEDs) are arranged is loaded on the first stage, and a target substrate is loaded on the second stage, the flatness measurement sensor to measure flatness of each of the transfer substrate and the target substrate, and adjust a height of at least one of the first stage or the second stage based on the flatness.

Abstract: Techniques related to a 5th generation (5G) or pre-5G communication system to support higher data rates after a 4th generation (4G) communication system such as long term evolution (LTE) ae provided. A reflector is provided that is configured to change a direction of a beam incident in a first direction to a second direction different from the first direction, so that a receiving entity positioned in a shadow area caused by an object can receive the beam. Therefore, the reflector removes the shadow area at which the beam does not arrive in a 5G wireless communication system.
