Abstract
Chip-on-chip interconnections of varied characteristics, such as varied diameters, heights and/or composition, are disclosed. A first chip-on-chip interconnection on a joining plane has a first characteristic (e.g., a first height) and a second chip-on-chip interconnection on the same joining plane has a second characteristic (e.g., a second height greater than the first height). The first and second characteristics of the chip-on-chip interconnections allow for chip-on-chip connections to other packages, substrates or chips of different levels and/or compositions.
