MicroLED devices can be transferred in large numbers to form microLED displays using processes such as pick-and-place, thermal adhesion transfer, or fluidic transfer. A blanket solder layer can be applied to connect the bond pads of the microLED devices to the terminal pads of a support substrate. After heating, the solder layer can connect the bond pads with the terminal pads in vicinity of each other. The heated solder layer can correct misalignments of the microLED devices due to the transfer process.

An electrode connection structure includes: a first electrode of an electrical circuit; and a second electrode of the electrical circuit that is electrically connected to the first electrode. The first and second electrodes are oppositely disposed in direct or indirect contact with each other. A plated lamination is substantially uniformly formed by plating process from a surface of a contact region and opposed surfaces of the first and second electrodes. A void near the surface of the contact region is filled by formation of the plated lamination. Portions of the plated lamination formed from the opposed surfaces of the first and second electrodes in a region other than the contact region are not joined together.
