DUAL-SIDE COOLING SEMICONDUCTOR PACKAGES AND RELATED METHODS

A dual-side cooling (DSC) semiconductor package includes a first metal-insulator-metal (MIM) substrate having a first insulator layer, first metallic layer, and second metallic layer. A second MIM substrate includes a second insulator layer, third metallic layer, and fourth metallic layer. The third metallic layer includes a first portion having a first contact area and a second portion, electrically isolated from the first portion, having a second contact area. A semiconductor die is coupled with the second metallic layer and is directly coupled with the third metallic layer through one or more solders, sintered layers, electrically conductive tapes, solderable top metal (STM) layers, and/or under bump metal (UBM) layers. The first contact area is electrically coupled with a first electrical contact of the die and the second contact area is electrically coupled with a second electrical contact of the die. The first and fourth metallic layers are exposed through an encapsulant.

Composite assembly of three stacked joining partners

A composite assembly of three stacked joining partners, and a corresponding method. The three stacked joining partners are materially bonded to one another by an upper solder layer and a lower solder layer. An upper joining partner and a lower joining partner are fixed in their height and have a specified distance from one another. The upper solder layer is fashioned from a first solder agent, having a first melt temperature, between the upper joining partner and a middle joining partner. The second solder layer is fashioned from a second solder agent, having a higher, second melt temperature, between the middle joining partner and the lower joining partner. The upper joining partner has an upwardly open solder compensating opening filled with the first solder agent, from which, to fill the gap between the upper joining partner and the middle joining partner, the first solder agent subsequently flows into the gap.
