  • Publication number: 20030139020
    Abstract: A semiconductor die package is disclosed. In one embodiment, the semiconductor die package includes a circuit substrate including a conductive region. A semiconductor die is on the circuit substrate. The semiconductor die includes an edge and a recess at the edge. A solder joint couples the semiconductor die and the conductive region through the recess.

  • Publication number: 20020171126
    Abstract: A packaging arrangement for a semiconductor device including a leadframe and a die coupled thereto. The die is coupled to the leadframe such that its back surface (drain area) is coplanar with source leads and a gate lead extending from the leadframe. A stiffener is coupled to the leadframe and electrically isolated therefrom in order to help maintain the position of the source and gate pads of the leadframe. When the semiconductor device is coupled to a printed circuit board (PCB), the exposed surface of the die serves as the direct drain connections while the source leads and gate leads serve as the connections for the source and gate regions of the die.

  • Publication number: 20020125550
    Abstract: A semiconductor device including a leadframe and two stacked dies, a first of which is on a top surface of a leadframe while the second one is on a bottom surface of the leadframe. The drain region of the first die is coupled to a drain clip assembly that includes a drain clip that is in contact with a lead rail. The body of the semiconductor device includes a window or opening that exposes the drain region of the second die.
