  • Patent number: 7364784
    Abstract: Provided is a thin semiconductor package comprising a semiconductor chip and a lead frame, the lead frame including a paddle portion configured for mounting the semiconductor chip in a manner that exposes bonding pads within an aperture formed in a center portion of the lead frame and a peripheral terminal pad portion for establishing external contacts. A plurality of bonding wires are used to establish electrical connection between a lower surface of the paddle part and corresponding bonding pads with intermediate leads providing connection to the terminal pad portions. The semiconductor chip, lead frame and bonding wires may then be encapsulated to form a thin semiconductor package having a thickness substantially equal to that of the terminal pad portions. The thin semiconductor packages may, in turn, be used to form multi-chip stack packages using known good semiconductor chips to form a high-density compound semiconductor packages.

  • Publication number: 20050212099
    Abstract: The present invention provides an LOC package wherein the lead frame is in direct contact with the semiconductor device. The lead frame, which includes openings, is positioned directly on the semiconductor device. An adhesive material is applied in the opening in the lead frame. This adhesive material contacts both the lead frame and the semiconductor device. The lead frame is therefore securely held to the semiconductor device. Wires can then be bonded to contact pads on the semiconductor device and to the lead frame.
