摘要： An apparatus is described that includes a substrate and a mold compound disposed on the substrate. The semiconductor die is embedded within the mold compound and is electrically coupled to lands on the substrate. Solder balls are disposed around the semiconductor die on the substrate. Each of the solder balls have a solid coating thereon. The solid coating contains a cleaning agent to promote its solder ball's coalescence with another solder ball. Respective vias are formed in the mold compound that expose the solder balls and their respective solid coatings. In combined or alternate embodiments outer edges of the mold compound have smaller thickness than regions of the mold compound between the vias and the semiconductor die. In combined or alternate embodiments micro-channels exist between the solder balls and the mold compound.

摘要翻译： 描述了一种包括设置在基板上的基板和模具化合物的装置。 半导体管芯被嵌入在模具化合物内并且电耦合到衬底上的焊盘。 焊球围绕半导体管芯设置在基板上。 每个焊球上都有一个固体涂层。 固体涂层含有一种清洁剂，以促进其焊球与另一种焊球的聚结。 在模具化合物中形成了暴露焊球及其各自固体涂层的通孔。 在组合或替代实施例中，模具化合物的外边缘具有比通孔和半导体管芯之间的模具化合物区域更小的厚度。 在组合或替代实施例中，焊料球与模具化合物之间存在微通道。
