摘要
A method of forming a bonding assembly that includes positioning a plurality of polymer spheres against an opal structure and placing a substrate against a second major surface of the opal structure. The opal structure includes the first major surface and the second major surface with a plurality of voids defined therebetween. The plurality of polymer spheres encapsulates a solder material disposed therein and contacts the first major surface of the opal structure. The method includes depositing a material within the voids of the opal structure and removing the opal structure to form an inverse opal structure between the first and second major surfaces. The method further includes removing the plurality of polymer spheres to expose the solder material encapsulated therein and placing a semiconductor device onto the inverse opal structure in contact with the solder material.
