  • Patent number: 8980696
    Abstract: A method of packaging a semiconductor die includes the use of an embedded ground plane or drop-in embedded unit. The embedded unit is a single, stand-alone unit with at least one cavity. The embedded unit is placed on and within an encapsulation area of a process mounting surface. The embedded unit may have different sizes and shapes and a number of different cavities that can be placed in a predetermined position on a substrate, panel or tape during processing of semiconductor dies that are embedded into redistributed chip package (RCP) or wafer level package (WFL) panels. The embedded unit provides the functionality and design flexibility to run a number of embedded units and semiconductor dies or components having different sizes and dimensions in a single processing panel or batch and reduces die drift, movement or skew during encapsulation and post-encapsulation cure.

  • Patent number: 8927417
    Abstract: A mechanism is provided by which signal travel distance within and between semiconductor device packages is reduced and substrate size and complexity can be reduced. This capacity is provided by virtue of a conductive via that intersects a wire bond molded within a package substrate. The via provides a direct electrical connection between an external signal transmitter or receiver and the points connected by the wire bond, and thereby avoiding the need for the signal to transit built up interconnects in the semiconductor device package. Conductive vias can provide connectivity through or to a package substrate, and can be through vias or blind vias. The conductive via is formed by either mechanical or laser drilling, and is filled using standard fill techniques, and is therefore readily incorporated into a package production flow.
