A carrier substrate is thereafter attached to the laser-ablative adhesive layer. The back side of the semiconductor substrate is thinned by polishing or grinding, during which the carrier substrate provides mechanical support to enable thinning of the semiconductor substrate to a thickness of about 25 ?m. A film frame tape is attached to the back side of the thinned semiconductor substrate and the laser-ablative adhesive layer is ablated by laser, thereby dissociating the carrier substrate from the back side of the C4 grind tape. The assembly of the film frame tape, the thinned semiconductor substrate, and the C4 grind tape is diced.

    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.

  • Publication number: 20110001230
    Abstract: Adequate heat dissipation is essential for semiconductor devices. When a device exceeds a specified junction temperature, the device can be damaged, not perform correctly, or can have a reduced operating life. Semiconductor packages must dissipate heat from the chip to the external environment (i.e. to the PCB, air, etc) to keep the semiconductor device below a certain temperature threshold. For most devices, the most efficient way to dissipate the heat is through the package external I/O connections and into the PCB that it is mounted to. For Ball Grid Array (BGA) packages, the external I/Os are solder balls. Variable pitch packages pose advantages in heat dissipation without introducing significant costs.
