发明名称 DEVICE HAVING A BONDING STRUCTURE FOR TWO ELEMENTS
摘要 A device and a method for bonding elements are described. A first solder ball is produced on a main surface of a first element. A second solder ball is produced on a main surface of a second element. Contact is provided between the first solder ball and the second solder ball. The first and second elements are bonded by applying a reflow act whereby the solder balls melt and form a joined solder ball structure. Prior to the bonding, the first solder ball is laterally embedded in a first layer of non-conductive material and the second solder ball is laterally embedded in a second layer of non-conductive material, such that the upper part of the first solder ball and upper part of the second solder ball are not covered by the non-conductive material. A third solder volume is applied on one or both of the embedded first or second solder balls, prior to the bonding.
