  • Publication number: 20240128097
    Abstract: A chip ejector may include an ejector body and a pushing mechanism, the ejector body may include first vacuum holes, an opening and at least one second vacuum hole, the first vacuum holes may fix a film having at least one semiconductor chip using a vacuum, the opening may be formed under the semiconductor chip, the second vacuum hole may be arranged around the opening to provide a portion of the film under an edge portion of a lower surface of the semiconductor chip with the vacuum, the pushing mechanism may be lifted in the ejector body through the opening to lift up the semiconductor chip and the film, thus, a sufficiently strong downward force may be applied to the portion of the film under the edge portion of the lower surface of the semiconductor chip to readily delaminate the semiconductor chip having a thin thickness from the film.
