  • Patent number: 11600556
    Abstract: Disclosed is a semiconductor package comprising a semiconductor chip, a first chip pad on a bottom surface of the semiconductor chip and adjacent to a first lateral surface in a first direction of the semiconductor chip, the first lateral surface separated from the first chip pad from a plan view in a first direction, and a first lead frame coupled to the first chip pad. The first lead frame includes a first segment on a bottom surface of the first chip pad and extending from the first chip pad in a second direction opposite to the first direction and away from the first lateral surface of the semiconductor chip, and a second segment which connects to a first end of the first segment and then extends along the first direction to extend beyond the first lateral surface of the semiconductor chip after passing one side of the first chip pad, when viewed in the plan view.
