Abstract

A semiconductor package or device includes a leadframe defining a plurality of leads which are arranged and partially etched in a manner facilitating a substantial reduction in burr formation resulting from a saw singulation process used to complete the fabrication of the semiconductor device. In one embodiment, the semiconductor device includes a die pad defining multiple peripheral edge segments. In addition, the semiconductor device includes a plurality of leads that are provided in a prescribed arrangement. At least one semiconductor die is connected to the top surface of the die pad and further electrically connected to at least some of the leads. At least portions of the die pad, the leads, the lands, and the semiconductor die are encapsulated by the package body, with at least portions of the bottom surfaces of the die pad and the leads being exposed in a common exterior surface of the package body.
