Abstract: A chuck table includes a support part receiving a package substrate. The package substrate includes a package area having semiconductor packages arranged thereon and a scrap area surrounding the package area. A package pad part is between the support part and the package substrate and directly contacts the package area. A scrap pad part is disposed between the support part and the package substrate and directly contacts the scrap area. A vacuum pipe extends through the package pad part and extends into the support part. The vacuum pipe has vacuum pressure applied thereto and has the vacuum pressure released therefrom. A fixing device is connected to the vacuum pipe. The fixing device moves closer to an upper surface of the scrap area as the vacuum pressure is applied to the vacuum pipe, and moves away from the upper surface of the scrap area as the vacuum pressure is released.
