Abstract:
1. A method of making an electronic device with a redistribution layer comprising: providing an electronic device having a first pattern of contact areas; forming a redistribution layer on a temporary substrate and comprising a first layer having a second pattern of contact areas matching the first pattern of contact areas, a third layer having a third pattern of contact areas different than the second pattern of contact areas, and a second layer having a pattern of interconnecting portions coupling the second pattern of contact areas to the third pattern of contact areas, with each interconnecting portion having a second pattern of contact area portion and a third pattern of contact area portion coupled thereto so that the second and third pattern of contact area portions are laterally offset from one another, with a size of the temporary substrate corresponding to a size of a plurality of electronic devices; coupling the first pattern of contact areas of the electronic device to the second pattern of contact areas of the redistribution layer; dividing the temporary substrate with the electronic device coupled thereto before removing the temporary substrate; and removing the temporary substrate from the redistribution layer to thereby form a redistributed electronic device.
