Abstract: A multichip module has a substrate, which receives several flip chip and for other semiconductor die on one surface and has vias extending through the substrate from the flip chip bottom electrodes to solder ball electrodes on the bottom of the substrate. Passive components are also mounted on the top of the substrate and are connected to further vias which extend to respective ball contacts at the substrate bottom. In one embodiment, the bottom surfaces and electrodes of the die are insulated and their tops (and drain electrodes) are connected by a moldable conductive layer. In another embodiment the top surface of the substrate is covered by an insulation cap, which may be finned for improved thermal properties. The passives are upended to have their longest dimension perpendicular to the substrate surface and are between the fin valleys. The insulation cover is a cap which fits over the top of the substrate, with mold lock depressions contained in the junction between the cap peripheral interior edge and the substrate mating edge surfaces.

Abstract translation: 多芯片模块具有基板，其在一个表面上接收多个倒装芯片和其它半导体管芯，并且具有从倒装芯片底部电极延伸穿过基板的通孔到基板底部的焊球电极。 被动元件也安装在基板的顶部，并且连接到在基板底部延伸到相应的滚珠触点的另外的通孔。 在一个实施例中，管芯的底表面和电极是绝缘的，并且它们的顶部（和漏电极）通过可模制导电层连接。 在另一个实施例中，衬底的顶表面由绝缘帽覆盖，绝缘帽可以被翅片以改善热性能。 无源器件具有垂直于衬底表面的最长尺寸，并且位于翅片谷之间。 绝缘盖是适合于基板顶部的盖，其中模具锁定凹陷包含在盖周边内部边缘和基板配合边缘表面之间的连接处。
