Abstract
An anti-cracking suction device for Czochralski single crystal is provided, wherein the device includes an outer cylinder, an inner cylinder disposed in the outer cylinder, a suction tube, and a first gap. An upper portion of the suction tube extends into the inner cylinder from a bottom of the outer cylinder, a lower portion of the suction tube is disposed outside the outer cylinder. The first gap is disposed between a bottom of the inner cylinder and the outer cylinder, and is configured to cushion a thermal expansion of the bottom of the inner cylinder to reduce stress at where the suction tube is connected with the inner cylinder, in a case that silicon liquid is sucked into the inner cylinder by the suction tube and accumulated at the bottom of the inner cylinder.
