    Abstract: An insulative substrate includes a plurality of flexible retaining clips and a plurality of alignment and retaining pins. A metal leadframe includes a plurality of leads. Each lead terminates in a spring contact beam portion. The leadframe is attached to the substrate (for example, by fitting a hole in each lead over a corresponding alignment and retaining pin and then thermally deforming the pin to hold the lead in place). An integrated circuit is press-fit down through the retaining clips such that pads on the face side of the integrated circuit contact and compress the spring contact beams of the leads. After the press-fit step, the retaining clips hold the integrated circuit in place. The resulting assembly is encapsulated. In a cutting and bending step, the leads are singulated and formed to have a desired shape. The resulting low-cost package involves no wire-bonding and no flip-chip bond bump forming steps.

  • Patent number: 6967357
    Abstract: A voltage-driven power semiconductor device includes a voltage-driven IEGT chip, a collector electrode plate, an emitter electrode plate, and an inductance material. The collector electrode plate is connected to the collector of the IEGT chip, and press-contacts the IEGT chip from its collector side. The emitter electrode plate press-contacts the IEGT chip from its emitter side. The inductance material has an inductance component and connects the emitter of the IEGT chip and the emitter electrode plate. In the voltage-driven power semiconductor device having this arrangement, an induced electromotive force is generated in the inductance material arranged between the emitter of the IEGT chip and the emitter electrode plate. This induced electromotive force can suppress a steep current change (di/dt) upon an OFF operation, and can further suppress a steep voltage change (dv/dt) caused by the current change (di/dt).

  • Patent number: 6946744
    Abstract: A mounting structure for a semiconductor die that reduces die attach strain within the die attach material without sacrificing the electrical and thermal characteristics of the package. In one embodiment, the mounting structure comprises a die attach metallization layer, a solder mask, and a layer of die attach material. The solder mask forms a solder pattern over the top surface of the die attach metallization layer. The solder pattern covers a portion of the die attach metallization layer to create multiple exposed areas of the die attach metallization layer. Each exposed area is separated by the solder mask and is located under the semiconductor die when the semiconductor die is secured to the mounting structure. A layer of die attach material covers the solder pattern and fills in each one of the exposed areas to form a semiconductor die mounting surface. In another embodiment, the die attach metallization layer is divided into multiple, spaced-apart die attach pads that are electrically coupled together.

  • Patent number: 6875931
    Abstract: An apparatus to retain an assembled component on one side of a double-sided printed circuit board during reflow of other components subsequently positioned on an opposite side of the double-sided printed circuit board and methods for manufacturing and using the same. The retainer includes a heat-expandable member and a retainer member. Being formed from a heat-expandable material, the heat-expandable member is coupled with the retainer member and is disposed about a periphery thereof. The retainer member is configured to be coupled with a component and, when the component is assembled onto a double-sided printed circuit board, to be received by an opening formed in the double-sided printed circuit board. The heat-expandable member is configured to expand during assembly of the component, engaging an inner surface that defines the opening. Thereby, the component is retained and supported when the double-sided printed circuit board is subsequently inverted, populated, and reflowed.

  • Patent number: 6844631
    Abstract: A bond pad (10) has a probe region (14) and a wire bond region (12) that are substantially non-overlapping. In one embodiment, the bond pad (10) is connected to a final metal layer pad (16) and extends over an interconnect region (24). The bond pad (10) is formed from aluminum and the final metal layer pad (16) is formed from copper. Separating the probe region (14) from the wire bond region (12) prevents the final metal layer pad (16) from being damaged by probe testing, allowing for more reliable wire bonds. In an application requiring very fine pitch between bond pads, the probe regions (14) and active regions (12) of a plurality of bond pads formed in a line may be staggered to increase the distance between the probe regions (14). In addition, forming the bond pads (10) over the interconnect region (24) reduces the size of the integrated circuit.
