Abstract
Embodiments of the invention provide fabrication processes for the co-fabrication of microprobe arrays along with one or more space transformers wherein the fabrication processes include the forming and adhering of a plurality of layers to previously formed layers and wherein at least a portion of the plurality of layers are formed from at least one structural material and at least one sacrificial material that is at least in part released from the plurality of layers after formation and wherein the space transformer includes a plurality of interconnect elements that connect one side to the array of probes that has a first spacing to another side that has a second spacing where the second spacing is greater than the first spacing. In some embodiments, the fabrication process includes a plurality of electrodeposition operations.
