    Abstract: A leadframe-based semiconductor package is proposed for the packaging of a semiconductor device, such as a multi-media card (MMC) chipset. The proposed semiconductor package is characterized by the use of a leadframe, rather than BT substrate or film, as the chip carrier for MMC chipset. The leadframe includes a supporting bar, a chip-supporting structure arranged at a downset position in relation to the supporting bar; and a plurality of leads, each lead including an outer-lead portion and an inner-lead portion; wherein the outer-lead portion is levelly linked to the supporting bar, while the inner-lead portion is arranged beside the chip-supporting structure and linked to the outer-lead portion via an intermediate-lead portion. The leadframe can be either the type having die pad or the type having no die pad. In the case of the type having die pad, a semiconductor chip is mounted on the die pad; and in the case of the type having no die pad, one or more semiconductor chips are mounted over an elongated part of the inner-lead portions of the leads. The use of leadframe allows the MMC package to be manufactured without having to include a lidding process, so that the MMC manufacture can be carried out in a less complex and more cost-effective manner.

    Abstract: An semiconductor device package (10) with improved thermal properties that limits unwanted parasitics and provides a more consistent distribution of parasitics from one device to another. The package of the present invention (10) is extremely compact and uses, in one embodiment, a minimal length of bond wires (20 and 22) between the terminals (14 and 16) and the attached device (30). The path length of the package (10) is reduced so as to represent only some fraction of a wavelength relative to the terminals (14 and 16) of the package (10). By reducing the length of the bond wires (20 and 22) and selecting the appropriate dielectric constant of the encapsulant (12), the invention provides a package (10) with a unique hexagonal structure that limits the effects of parasitics and provides good thermal dissipation. In a second and third embodiment of the present invention, the semiconductor device package (10) is useful in optoelectronic devices such light emitting diodes with an anode (71) and a cathode (72). The use of the novel design in this implementation also improves thermal properties and limits unwanted parasitics.

    Abstract: A lead frame that does not tie straps and a die bond pad is rectangular in shape, with the same number of lead frame leads (11) on opposite sides and a different number of lead frame lead frame leads (11) on adjacent sides. Lead frame leads (11) extend into the area in which the tie strap would normally be placed. A heat slug is (30) taped into the lead frame to provide a semiconductor die mount area. At least one lead (11) from one side of the lead frame, located where the tie strap is normally located, is connected via a bond wire (17a, 17b) to a bond pad (19) on the semiconductor die (18) on a side adjacent to the side where the lead frame lead is located.

    Abstract: Fixtures for attaching a semiconductor chip to a substrate. The semiconductor chip has an array of joining material bumps, such as C4 solder balls. The substrate has an array of conductive pads corresponding to the array of joining material bumps. In a first embodiment the fixture has a body having a first cavity for containing the semiconductor chip and a second cavity in communication with the first cavity for containing the substrate. Whereby the substrate is placed over the semiconductor chip with the conductive pads opposing and in contact with the joining material bumps, such that during reflow of the joining material bumps, the weight of the substrate acts against the joining material bumps and aids in the attachment of the semiconductor chip to the substrate to form electrical connections therebetween. In a second embodiment the fixture has a first plate having a first opening for disposal of the semiconductor chip therein, a second plate stacked below the first plate and having a thickness substantially equal to the thickness of the substrate, the second plate further having a second opening opposing the first opening for disposal of the substrate therein, and a third plate stacked below the second plate such that the substrate is flattened in the second opening under the weight of the first plate thereby aiding in the attachment of the joining material bumps to their corresponding conductive pads during solder reflow to form electrical connections therebetween. Methods for use of the fixtures is also provided.
