摘要:
An LGA structure is provided having at least one semiconductor device over a substrate and a mechanical load apparatus over the semiconductor device. The structure includes a load-distributing material between the mechanical load apparatus and the substrate. Specifically, the load-distributing material is proximate a first side of the semiconductor device and a second side of the semiconductor device opposite the first side of the semiconductor device. Furthermore, the load-distributing material completely surrounds the semiconductor device and contacts the mechanical load apparatus, the substrate, and the semiconductor device. The load-distributing material can be thermally conductive and comprises an elastomer and/or a liquid. The load-distributing material comprises a LGA interposer adapted to connect the substrate to a PCB below the substrate and/or a second substrate. Moreover, the load-distributing material comprises compressible material layers and rigid material layers. The load-distributing material comprises a rigid material incased in a compressible material.
