Abstract: Embodiments of the present invention relate to semiconductor device packages featuring encapsulated leadframes in electrical communication with a supported die through electrically conducting bumps or balls. By eliminating the need for a separate diepad and lateral isolation between an edge of the diepad and adjacent non-integral leads or pins, embodiments of packages fabricated by bump on leadframe (BOL) processes in accordance with embodiments of the present invention increase the space available to the die for a given package footprint. Embodiments of the present invention may also permit multiple die and/or multiple passive devices to occupy space in the package previously consumed by the diepad. The result is a flexible packaging process allowing the combination of die and technologies required for complete sub-systems in a conventional small JEDEC specified footprint.

Abstract: An improved semiconductor device is disclosed. In one embodiment, the semiconductor device includes a semiconductor chip with contact areas on the top or bottom surface. A first lead assembly, formed from a semi-rigid sheet of conductive material, has a lead assembly contact attached to one of the contact areas of the semiconductor chip. The first lead assembly also has at least one lead connected to and extending from the lead assembly contact. A second lead assembly, also formed from a semi-rigid sheet of conductive material, has a lead assembly contact attached to another one of the contact areas of the semiconductor chip. The second lead assembly also has at least one lead connected to and extending from the lead assembly contact. An encapsulant encloses the semiconductor chip, the lead assembly contact of the first lead assembly and the lead assembly contact of the second lead assembly.

Abstract: A multiple integrated circuit intra-package configuration having a centrally mounted integrated circuit die and an additional circuit device mounted in the package periphery. The additional circuit device may provide multiple functions, for example, to protect and enhance the performance of the integrated circuit die. Examples of such functions are electrostatic discharge protection circuits and temperature sensing. The intra-package circuit device avoids problems such as simple and complex process compatibility and additional space requirements of utilizing components external to the package. The multiple circuit intra-package configuration utilizes the small space available in the vicinity of lead posts in integrated circuit packages such as SOIC and TSSOP configurations to mount circuit devices. In one embodiment, a circuit device, for example, a diode, is mounted on a lead post and connected as desired using any of a variety of connectability alternatives such as wire bonding.
