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.
METHOD OF MANUFACTURING SEMICONDUCTOR DEVICES AND CORRESPONDING SEMICONDUCTOR DEVICE
A semiconductor chip is arranged over a substrate in the form of a leadframe. A set of current-carrying formations configured as conductive ribbons are coupled to the semiconductor chip. The substrate does not include electrically conductive formations for electrically coupling the conductive ribbons to each other. Electrical contacts are formed via wedge bonding, for instance, between adjacent ones of the conductive ribbons so that a contact is provided between the adjacent ones of the conductive ribbons in support of a multi-formation current-carrying channel.
SEMICONDUCTOR DEVICE AND A METHOD OF MANUFACTURE
A semiconductor device is provided, including a leadframe, a die attached to the leadframe using a first solder, a source clip and a gate clip attached to the die using a second solder, and a drain clip attached to the leadframe. The semiconductor device is inverted, so that the source clip and the gate clip are positioned on the bottom side of the semiconductor device, and the leadframe is positioned on the top side of the semiconductor device so that the leadframe is a top exposed drain clip. The source clip and/or the drain clip comprise a half cut locking feature. The half cut locking feature can be formed as a wing and located at the sides of the source clip and the gate clip.

A leadframe includes leads or lead terminals, a plurality of folded features including i) support features positioned within an area defined in at least one dimension by the leads or the lead terminals configured for supporting at least one of a die pad and a first pad and a second pad spaced apart from one another, or ii) current carrying features. At least one of the folded features includes a planar portion and a folded edge structure that curves upwards at an angle of at least 45° relative to the planar portion. The folded features are configured to provide an effective increase in thickness to reduce the deformation observed in assembly.
