Abstract: A method and apparatus for aligning a wafer using a laser scanner, and a semiconductor transfer device are provided. The method includes a laser irradiation operation of irradiating a laser toward the wafer using a laser scanner disposed on a rear side or a lower side of the wafer and obtaining an image, a dataset acquisition operation of obtaining location information of at least three wafer edges by using a distance corresponding to a laser irradiation direction to a wafer edge in the image, a calculation operation of calculating a center point of the wafer by using the obtained location information of the wafer edge, and a detection operation of detecting whether a calculated center point is within a preset tolerance range.

Abstract: An air conditioner includes a housing having a suction port and a discharge port, a main fan configured to draw air into the housing through the suction port and discharge air from the housing through the discharge port, an auxiliary fan configured to draw, into the housing, air discharged by the main fan and a controller configured to control a rotational speed of the auxiliary fan to change a direction in which air is discharged from the housing.
