Abstract: An arrangement increases the reliability of substrate-based Ball-Grid-Array (BGA) packages, with a die (chip) that is mounted on a substrate and electrically connected to interconnects of the substrate and for which the substrate is provided with solder balls arranged in a predetermined grid. The arrangement is particularly simple to realize and effective for increasing the reliability of substrate-based Ball-Grid-Array packages. This is achieved by a laminate layer provided with openings for receiving the solder balls at the positions of ball pads being laminated on the side of the substrate that is provided with the interconnects.

Abstract: A packaged electronic component includes a substrate with an upper layer, a lower layer and a middle layer between the upper layer and the lower layer. The middle layer is formed from a first material that is more flexible than the material of the upper layer and the material of the lower layer. An electronic component, such as a semiconductor chip, can be adhered over the upper layer of the substrate. Solder balls can be adhered over the lower layer of the substrate.

Abstract: Connecting elements on semiconductor chips for semiconductor components and methods for producing connecting elements provide electrical connections between contact areas of a semiconductor chip and contact pads of a superordinate circuit board. The connecting elements have a bent metal strip with two metal limbs with flattened limb ends. One of the two limb ends is electrically connected to the contact areas, while the second limb end is elastically supported on the top side of the semiconductor chip.

Abstract: The invention relates to an electronic device having a stack of semiconductor chips, and to a method for the production thereof. A first semiconductor chip is arranged on a rewiring substrate, and at least one semiconductor stack chip is arranged on the first semiconductor chip. A rewiring plane is arranged between the semiconductor chips. The contact areas of the semiconductor chips are connected to external contacts of the device by the rewiring plane and the rewiring substrate.
