    摘要: In one embodiment, a semiconductor package includes a generally planar die paddle or die pad that defines multiple peripheral edge segments, and includes one or more tie bars protruding therefrom. In addition, the semiconductor package includes a plurality of leads, portions of which protrude from respective side surfaces of a package body of the semiconductor package. Connected to the top surface of the die pad is at least one semiconductor die which is electrically connected to at least some of the leads. At least portions of the die pad, the leads, and the semiconductor die are encapsulated by the package body. The one or more tie bars and the plurality of leads include downsets that are sized and oriented relative to each other to facilitate enhanced manufacturing.

    摘要: Disclosed is a lead frame and a semiconductor device including the same. The lead frame is provided with a die pad, and first, second and third lands sequentially arranged on an outer circumferential edge. The lead frame can separate the first and second lands or the die pad and the first land using a plating layer formed on the lead frame as a mask, instead of using a separate mask by etching after the application of the encapsulant. As a result thereof, a plurality of lands can be formed at low cost, in comparison with a conventional method. Additionally, the first, second and third lands are exposed to the outside through a lower portion of an encapsulant, and can be surface mounted on an external device through the first, second and third lands. A plating layer formed on bottom surfaces of the first, second and third lands of the lead frame and a process for separately plating nickel (Ni)/gold (An), Ni/Pd/Au, or tin (Sn) can be omitted so as to easily surface mount the semiconductor device to the external device.

    摘要: In accordance with the present invention, there is provided a semiconductor package (e.g., a QFP package) including a uniquely configured leadframe sized and configured to maximize the available number of exposed leads in the semiconductor package. More particularly, the semiconductor package of the present invention includes a generally planar die pad or die paddle defining multiple peripheral edge segments. In addition, the semiconductor package includes a plurality of leads. Some of these leads include exposed bottom surface portions which are provided in at least two concentric rows or rings which at least partially circumvent the die pad, with other leads including portions which protrude from respective side surfaces of a package body of the semiconductor package. Connected to the top surface of the die pad is at least one semiconductor die which is electrically connected to at least some of the leads. At least portions of the die pad, the leads, and the semiconductor die are encapsulated by the package body, with at least portions of the bottom surfaces of the die paddle and some of the leads being exposed in a common exterior surface of the package body.
